Implementations§

Source§

impl PackingConstants

Source

pub(crate) fn new(name: &Ident) -> Self

Create packing constant helper struct

Source

pub(crate) fn slot(&self) -> Ident

The bare field name constant (U256 slot, used by #[contract] macro)

Source

pub(crate) fn location(&self) -> Ident

The _LOC suffixed constant

Source

pub(crate) fn offset(&self) -> Ident

The _OFFSET constant identifier

Source

pub(crate) fn into_tuple(self) -> (Ident, Ident)

Returns the constant identifiers required by both macros (slot, offset)

The type returned in the event of a conversion error.
Source§

fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>

Performs the conversion.

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.
