Trait ZeroCopy 

pub unsafe trait ZeroCopy<C: ConfigCore>: 'static {
    // Provided methods
    fn from_bytes<'de>(bytes: &'de [u8], config: C) -> ReadResult<&'de Self>
       where Self: SchemaRead<'de, C, Dst = Self> + Sized { ... }
    fn from_bytes_mut<'de>(
        bytes: &'de mut [u8],
        config: C,
    ) -> ReadResult<&'de mut Self>
       where Self: SchemaRead<'de, C, Dst = Self> + Sized { ... }
}

Marker trait for types that can be deserialized via direct borrows from a Reader.

You should not manually implement this trait for your own type unless you absolutely know what you're doing. The derive macros will automatically implement this trait for your type if it is eligible for zero-copy deserialization.

Safety

• The type must not have any invalid bit patterns, no layout requirements, no endianness checks, etc.

Provided Methods

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.

Implementors

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.
