Struct redwm::imports::QueryExtensionRequest

pub struct QueryExtensionRequest<'input> {
    pub name: Cow<'input, [u8]>,
}

check if extension is present.

Determines if the specified extension is present on this X11 server.

Every extension has a unique major_opcode to identify requests, the minor opcodes and request formats are extension-specific. If the extension provides events and errors, the first_event and first_error fields in the reply are set accordingly.

There should rarely be a need to use this request directly, XCB provides the xcb_get_extension_data function instead.

Fields

• name_len - The length of name in bytes.
• name - The name of the extension to query, for example “RANDR”. This is case sensitive!

See

• xdpyinfo: program
• xcb_get_extension_data: function

Fields

name: Cow<'input, [u8]>
