impl StructuralPartialEq for FixInt

impl<C: ConfigCore> ZeroCopy<C> for FixInt

where C::ByteOrder: PlatformEndian,

Convenience to allow trait implementations to hook into the configured IntEncoding and conditionally enable ZeroCopy.

For example, if a SchemaRead / SchemaWrite implementation delegates its integer encoding to the configuration’s IntEncoding, it can constrain its ZeroCopy bound by that encoding.

fn from_bytes<'de>(bytes: &'de [u8], config: C) -> ReadResult<&'de Self>

where Self: SchemaRead<'de, C, Dst = Self> + Sized,

Like crate::ZeroCopy::from_bytes, but allows the caller to provide a custom configuration.

fn from_bytes_mut<'de>( bytes: &'de mut [u8], config: C, ) -> ReadResult<&'de mut Self>

where Self: SchemaRead<'de, C, Dst = Self> + Sized,

Like crate::ZeroCopy::from_bytes_mut, but allows the caller to provide a custom configuration.
