Enum Format

#[repr(i32)]
pub enum Format {
    InvalidFormat = 0,
    Dense = 1,
    Sparse = 2,
}

A format specifies the method used by a layout to store an array in memory.

Variants

InvalidFormat = 0

TODO(b/120869032): Rename this to FORMAT_NONE or something else which better corresponds to its meaning.

Dense = 1

The default layout, with exactly one storage location per element.

Sparse = 2

A sparsely encoded layout, providing only the index/value pairs of non-zero elements.

Implementations

impl Format

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of Format.

pub fn from_i32(value: i32) -> Option<Format>

Converts an i32 to a Format, or None if value is not a valid variant.

Trait Implementations

impl Clone for Format

fn clone(&self) -> Format

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Format

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

Formats the value using the given formatter.

impl Default for Format

fn default() -> Format

Returns the “default value” for a type.

impl From<Format> for i32

fn from(value: Format) -> i32

Converts to this type from the input type.

impl Hash for Format

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,

Feeds a slice of this type into the given Hasher.

impl Ord for Format

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Format

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Format

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
