Struct Config 

pub struct Config<'d> {
    pub max_packet_size: u16,
    pub min_width: u32,
    pub max_width: u32,
    pub min_height: u32,
    pub max_height: u32,

    pub formats: &'d [PixelFormat],
    pub supported_rotations: u8,
    pub connectors: &'d [GudConnector<'d>],
    pub validate_mode_blocking: fn(connector: u8, mode: &DisplayMode) -> bool,
}

Static class driver configuration passed to GudClass::new.

This configuration is fixed when the class is created.

Fields

max_packet_size: u16

Maximum packet size for the bulk OUT endpoint: 8..=64 for full-speed, 512 for high-speed.

min_width: u32

Minimum framebuffer width the device handles.

max_width: u32

Maximum framebuffer width.

min_height: u32

Minimum framebuffer height.

max_height: u32

Maximum framebuffer height.

max_buffer_size: u32

Maximum size in bytes of one damage rectangle. 0 means no cap. Does not have to fit in memory, it can be streamed chunk by chunk.

formats: &'d [PixelFormat]

Supported pixel formats, 1..=GUD_FORMATS_MAX_NUM.

supported_rotations: u8

ROTATION_* bitmask; 0 omits the rotation property entirely.

connectors: &'d [GudConnector<'d>]

Connectors, 1..=GUD_CONNECTORS_MAX_NUM. Index order is the index the host uses in wValue and SET_STATE_CHECK.

validate_mode_blocking: fn(connector: u8, mode: &DisplayMode) -> bool

Validate a mode for the given connector index during SET_STATE_CHECK.

Implementations

impl Config<'_>

pub fn control_buf_len(&self) -> usize

Minimum control buffer length for this configuration.

Takes the max over all control transfers.
