Enum Prim 

pub enum Prim {
    Bool,
    I8,
    I16,
    I32,
    I64,
    U8,
    U16,
    U32,
    U64,
    F32,
    F64,
    String,
    Bytes,
}

A fixed-width wire primitive inside a value buffer.

Every backend spells the read/write routine for one of these the same way modulo casing (read_i32, readI32, ReadI32), so the shared name helpers let a codec emitter dispatch on the whole set with one arm.

Variants

Bool

One byte, 0 or 1.

I8

One signed byte.

I16

Two bytes, little-endian, signed.

I32

Four bytes, little-endian, signed.

I64

Eight bytes, little-endian, signed.

U8

One unsigned byte.

U16

Two bytes, little-endian, unsigned.

U32

Four bytes, little-endian, unsigned.

U64

Eight bytes, little-endian, unsigned.

F32

Four bytes, IEEE 754 bits.

F64

Eight bytes, IEEE 754 bits.

String

A u32 byte length followed by UTF-8 bytes, no NUL terminator.

Bytes

A u32 length followed by raw bytes.

Implementations

impl Prim

pub const ALL: [Prim; 13]

Every primitive, for exhaustive tables in runtime preambles.

pub fn snake(self) -> &'static str

The lower-case spelling (bool, i32, string, bytes), the stem of snake-case routine names such as read_i32.

pub fn pascal(self) -> &'static str

The capitalized spelling (Bool, I32, String, Bytes), the stem of camel-case routine names such as readI32.

pub fn is_numeric(self) -> bool

true for the integer and float primitives (everything but bool, string, and bytes).

Trait Implementations

impl Clone for Prim

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Prim

impl Debug for Prim

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Eq for Prim

impl Hash for Prim

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,
