Struct gfx_hal::format::FormatDesc

pub struct FormatDesc {
    pub bits: u16,
    pub dim: (u8, u8),
    pub packed: bool,
    pub aspects: Aspects,
}

Description of a format.

Fields

bits: u16

Total number of bits.

• Depth/Stencil formats are opaque formats, where the total number of bits is unknown. A dummy value is used for these formats instead (sum of depth and stencil bits). For copy operations, the number of bits of the corresponding aspect should be used.
• The total number can be larger than the sum of individual format bits (color, alpha, depth and stencil) for packed formats.
• For compressed formats, this denotes the number of bits per block.

dim: (u8, u8)

Dimensions (width, height) of the texel blocks.

packed: bool

The format representation depends on the endianness of the platform.

• On little-endian systems, the actual oreder of components is reverse of what a surface type specifies.

aspects: Aspects
