VkCommandBufferUsageFlagBits

Bitmask specifying usage behavior for command buffer

Bits which can be set in VkCommandBufferBeginInfo::flags, specifying usage behavior for a command buffer, are:

typedef enum VkCommandBufferUsageFlagBits {
    VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT = 0x00000001,
    VK_COMMAND_BUFFER_USAGE_RENDER_PASS_CONTINUE_BIT = 0x00000002,
    VK_COMMAND_BUFFER_USAGE_SIMULTANEOUS_USE_BIT = 0x00000004,
    // Provided by extensions
    VK_COMMAND_BUFFER_USAGE_RESERVED_3_BIT_HUAWEI = 0x00000008,
    VK_COMMAND_BUFFER_USAGE_RESERVED_4_BIT_HUAWEI = 0x00000010,
} VkCommandBufferUsageFlagBits;

pub struct CommandBufferUsageFlagBits(u32);
impl CommandBufferUsageFlagBits {
    pub const ONE_TIME_SUBMIT: Self = 0x00000001;
    pub const RENDER_PASS_CONTINUE: Self = 0x00000002;
    pub const SIMULTANEOUS_USE: Self = 0x00000004;
    pub const RESERVED_3_HUAWEI: Self = 0x00000008;
    pub const RESERVED_4_HUAWEI: Self = 0x00000010;
}

VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT specifies that each recording of the command buffer will only be submitted once, and the command buffer will be reset and recorded again between each submission.
VK_COMMAND_BUFFER_USAGE_RENDER_PASS_CONTINUE_BIT specifies that a secondary command buffer is considered to be entirely inside a render pass. If this is a primary command buffer, then this bit is ignored.
VK_COMMAND_BUFFER_USAGE_SIMULTANEOUS_USE_BIT specifies that a command buffer can be resubmitted to any queue of the same queue family while it is in the pending state, and recorded into multiple primary command buffers.
