Primitive sample types supported by LERC.

This trait is sealed and implemented for i8, u8, i16, u16, i32, u32, f32, and f64.

Required Associated Constants

const DATA_TYPE: DataType

Corresponding runtime DataType.

const IS_INTEGER: bool

Whether this sample is an integer type.

Required Methods

fn from_f64(value: f64) -> Self

Converts an f64 with Rust’s primitive numeric-cast semantics.

fn to_f64(self) -> f64

Promotes the sample to f64.

fn read_le(bytes: &[u8]) -> Result<Self>

Reads one little-endian sample.

fn write_le(self, out: &mut Vec<u8>)

Appends one little-endian sample.

fn into_pixel_data(values: Vec<Self>) -> PixelData

Wraps a homogeneous buffer in PixelData.

Provided Methods

fn read_vec(bytes: &[u8]) -> Result<Vec<Self>>

Reads an aligned little-endian sample buffer.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
