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

impl Ord for FormatDesc

fn cmp(&self, other: &FormatDesc) -> Ordering

This method returns an Ordering between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<FormatDesc> for FormatDesc

fn eq(&self, other: &FormatDesc) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &FormatDesc) -> bool

This method tests for !=.

impl PartialOrd<FormatDesc> for FormatDesc

fn partial_cmp(&self, other: &FormatDesc) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &FormatDesc) -> bool

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.
