Cargo Features

[dependencies]
subxt-signer = { version = "0.35.3", default-features = false, features = ["std", "sr25519", "ecdsa", "subxt", "web", "native"] }

default = ecdsa, native, sr25519, std, subxt

These default features are set whenever subxt-signer is added without default-features = false somewhere in the dependency tree.

std default

Enables std of bip39, hmac, pbkdf2, regex, schnorrkel, secp256k1 ^0.28.2, sha2, sp-core ^31.0.0, and sp-crypto-hashing

regex:

ECOSYSTEM FEATURES

The 'std' feature permits the regex crate to use the standard library. This is intended to support future use cases where the regex crate may be able to compile without std, and instead just rely on 'core' and 'alloc' (for example). Currently, this isn't supported, and removing the 'std' feature will prevent regex from compiling.

sr25519 default = schnorrkel

Pick the signer implementation(s) you need by enabling the corresponding features. Note: I had more difficulties getting ecdsa compiling to WASM on my mac; following this comment helped: https://github.com/rust-bitcoin/rust-bitcoin/issues/930#issuecomment-1215538699

Affects subxt-signer::sr25519…

ecdsa default = secp256k1

Affects subxt-signer::ecdsa…

subxt default

Make the keypair algorithms here compatible with Subxt's Signer trait,
so that they can be used to sign transactions for compatible chains.

Enables subxt

web

The getrandom package is used via schnorrkel. We need to enable the JS feature on it if compiling for the web.

Enables web of optional subxt and js of getrandom

We only pull this in to enable the JS flag for schnorrkel to use.

native default

Enables native of optional subxt

subxt:

Enable this for native (ie non web/wasm builds).
Exactly 1 of "web" and "native" is expected.

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.

schnorrkel sr25519 std

secp256k1 ecdsa std

Enables secp256k1 ^0.28.2
