Function ecdsa_verify 

Source 
pub fn ecdsa_verify(
    sig: <PassPointerAndRead<&Signature, 65> as RIType>::Inner,

Expand description

Verify ecdsa signature.

Returns true when the verification was successful.

Note: This function does not enforce low-S signature normalization. Callers that require canonical (BIP-62 / EIP-2) signatures should check [sp_core::ecdsa::is_signature_normalized] before calling this function.
