luisschwab · 2026-01-07T15:36:51Z

Closes #142.
Closes #146.
Closes #148.
Closes #150.

This PR does a bunch of cleanup, standardizes and adds missing documentation, fixes inconsistencies and redundancies in the API, and uses rust-bitcoin types where possible.

Changelog

# Added
- Add `impl From<EsploraTx> to Transaction` and `impl From<&EsploraTx> to Transaction`
- Add `sat_per_vbyte_to_feerate` utility function in `api.rs`
- Add `get_block_infos` (returns `Vec<BlockInfo>`)

# Breaking
- Rename `scripthash_txs` to `get_scripthash_txs`
- Remove `PrevOut` in favor of reusing `Vout`
- Rename `Tx` to `EsploraTx`
- Remove `EsploraTx::fee()` method (use `EsploraTx.fee` instead)
- Remove `EsploraTx::weight()` method (use `Esplora.weight` instead)
- Change `get_fee_estimates` to return `HashMap<u16, FeeRate>` instead of `HashMap<u16, f64>`
- Change `convert_fee_rate` to accept `HashMap<u16, FeeRate>` and return `Option<FeeRate>` instead of `Option<f32>`
- Change `submit_package` `maxfeerate` parameter from `Option<f64>` to `Option<FeeRate>`
- Change `submit_package` `maxburnamount` parameter from `Option<f64>` to `Option<Amount>`
- Change all bitcoin amount fields from `u64` to `Amount`
- Change all weight fields from `u64` to `Weight`

# Changed
- Deprecate `BlockSummary` and `get_blocks` (to be removed on v0.14.0)
- Replace `std::` with `core::` where applicable
- Reorder API structs into logical groups: transaction, block, address, script hash, UTXO, mempool
- Reorder client methods into logical groups: transaction, block, address, script hash, mempool
- Improve documentation for `api.rs`, `async.rs`, `blocking.rs`, and `lib.rs`
- Update copyright notice to `2020-2026`

I'm also wondering on how disruptive it'll be on downstream, see VM's comment, though it'll be in a major release.

luisschwab · 2026-01-23T15:09:24Z

Makes sense. We can remove the deprecated function on v14.

I'll rebase this one since we decided to deprecate get_blocks instead of removing it outright.

Removes `BlockSummary`, as it omitted information returned by Esplora. This removes `get_blocks` and adds `get_block_infos` (`get_blocks` was deprecated in v0.12.3).

The `PrevOut` struct is identical to `Vout`.

Pushed 8337a89 completing the work. It's a big one, but mostly documentation and moving things around.

This commit: - Renames `Tx` to `EsploraTx`: more explicit. `Tx` is not precise about what it is. - Remove `EsploraTx::fee`, since the field is already public. - Implements `From<EsploraTx>`/`From<&EsploraTx>` to `Transaction` conversions. - Reorders structs into logical groups: Transaction, Block, Address, ScriptHash, UTXO, and Mempool. - Improves documentation. - Updates copyright notice to `2020-2026`.

This commit: - Reorders methods into logical groups: transaction, block, address, script hash, and mempool. - Improves documentation throughout: clearer summaries, consistent style, and proper intra-doc links. - Moves `Sleeper`, `DefaultSleeper`, and `is_status_retryable` to the top of the file for better readability. - Updates return types from `Tx` to `EsploraTx` following the rename. - Removes unused `log` imports. - Updates copyright notice to `2020-2026`.

This commit: - Changes `get_fee_estimates` to return `HashMap<u16, FeeRate>` instead of `HashMap<u16, f64>`. - Changes `convert_fee_rate` to accept `HashMap<u16, FeeRate>` and return `Option<FeeRate>` instead of `Option<f32>`. - Adds `sat_per_vbyte_to_feerate` to `api.rs` to convert the raw `f64` sat/vbyte values returned by the Esplora API into `FeeRate`. - Updates the `feerate_parsing` test accordingly.

This commit: - Rewrites crate-level docs: - Cleaner structure - Usage examples for async and blocking clients - Feature table instead of a bullet list - Improves `Builder` documentation - Improves `Error` documentation - Replaces `std::` with `core::` where applicable - Updates copyright notice to `2020-2026`

…_package`

Re-add with a deprecation warning. These should be removed for the v0.14.0 release.

Only casting to `u64` would always round down. Rounding (`.round()`) and then casting to `u64` is more precise. Also updates the fee JSON on `test_feerate_parsing` with current values which include sub-1 sat fees: ``` curl https://mempool.space/api/fee-estimates | jq 'to_entries | sort_by(.key | tonumber) | from_entries' ```
