Enum vulkano::command_buffer::CommandBufferUsage

#[repr(u32)]
pub enum CommandBufferUsage {
    OneTimeSubmit,
    MultipleSubmit,
    SimultaneousUse,
}

Usage flags to pass when creating a command buffer.

The safest option is SimultaneousUse, but it may be slower than the other two.

Variants

OneTimeSubmit

The command buffer can only be submitted once before being destroyed. Any further submit is forbidden. This makes it possible for the implementation to perform additional optimizations.

MultipleSubmit

The command buffer can be used multiple times, but must not execute or record more than once simultaneously. In other words, it is as if executing the command buffer borrows it mutably.

SimultaneousUse

The command buffer can be executed multiple times in parallel on different queues. If it’s a secondary command buffer, it can be recorded to multiple primary command buffers at once.

Trait Implementations

impl Clone for CommandBufferUsage

fn clone(&self) -> CommandBufferUsage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CommandBufferUsage

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

Formats the value using the given formatter.

impl From<CommandBufferUsage> for CommandBufferUsageFlags

fn from(val: CommandBufferUsage) -> Self

Converts to this type from the input type.

impl Ord for CommandBufferUsage

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<CommandBufferUsage> for CommandBufferUsage

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

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

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

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

impl PartialOrd<CommandBufferUsage> for CommandBufferUsage

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

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

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

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

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

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

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

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

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

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