#### fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for

`self`

and `other`

) and is used by the `<=`

operator. Read moresource§### impl TypeMarker for Errno

### impl TypeMarker for Errno

source§#### fn inline_align(_context: Context) -> usize

#### fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the
encoded object. It must be a (nonzero) power of two.

source§#### fn inline_size(_context: Context) -> usize

#### fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including
padding for alignment. Must be a multiple of

`inline_align`

#### fn encode_is_copy() -> bool

Returns true if the memory layout of

`Self::Owned`

matches the FIDL wire
format and encoding requires no validation. When true, we can optimize
encoding arrays and vectors of `Self::Owned`

to a single memcpy. Read moresource§#### fn decode_is_copy() -> bool
