Cargo Features
[dependencies]
subxt-signer = { version = "0.38.0", default-features = false, features = ["std", "sr25519", "ecdsa", "unstable-eth", "polkadot-js-compat", "subxt", "web"] }- default = ecdsa, sr25519, std, subxt
-
These default features are set whenever
subxt-signeris added withoutdefault-features = false - std default polkadot-js-compat?
-
Enables std of sha2, optional serde, and optional serde_json
serde:
These are used if the polkadot-js-compat feature is enabled
and std of bip39, hmac, pbkdf2, regex, optional base64, optional crypto_secretbox, optional schnorrkel, optional scrypt, and optional secp256k1
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 polkadot-js-compat? = 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 unstable-eth? = secp256k1
-
Affects
subxt-signer::ecdsa… - unstable-eth = bip32, ecdsa, keccak-hash, secp256k1
-
Affects
subxt-signer::eth… - polkadot-js-compat = base64, crypto_secretbox, scrypt, serde, serde_json, sr25519, std, subxt
-
Enable support for loading key pairs from polkadot-js json.
Affects
subxt-signer::polkadot_js_compat… - subxt default polkadot-js-compat?
-
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-core
- web
-
The getrandom package is used via schnorrkel. We need to enable the JS feature on it if compiling for the web.
We only pull this in to enable the JS flag for schnorrkel to use.
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.
