InvalidSignature(InvalidSignature)

Implementations§

impl ITIP20Errors

pub const SELECTORS: &'static [[u8; 4]]

All the selectors of this enum.

Note that the selectors might not be in the same order as the variants. No guarantees are made about the order of the selectors.

pub const SIGNATURES: &'static [&'static str]

The signatures in the same order as SELECTORS.
