Implementations

impl Permit2Errors

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.

Prefer using SolInterface methods instead.

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

The names of the variants in the same order as SELECTORS.

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

The signatures in the same order as SELECTORS.

pub fn signature_by_selector(selector: [u8; 4]) -> Option<&'static str>

Returns the signature for the given selector, if known.

pub fn name_by_selector(selector: [u8; 4]) -> Option<&'static str>

Returns the enum variant name for the given selector, if known.

impl Permit2Errors

pub fn allowance_expired(deadline: U256) -> Self

Creates a AllowanceExpired error.

error AllowanceExpired(uint256)

pub fn excessive_invalidation() -> Self

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
