Struct lv2rs_urid::Unmap

#[repr(C)]
pub struct Unmap {
    pub handle: MapHandle,
    pub unmap: extern "C" fn(handle: UnmapHandle, urid: URID) -> *const c_char,
}

Struct for mapping URIDs to URIs.

Fields

handle: MapHandle

Pointer to a host-specific handle to map URIDs to URIs.

unmap: extern "C" fn(handle: UnmapHandle, urid: URID) -> *const c_char

Function that maps a URID to a URI.

Methods

impl Unmap

pub fn try_from_features(features: &FeaturesList) -> Option<&'static mut Self>

Try to find the unmapping feature in the features map.

If this function returns None if the host does not support unmapping.

pub fn unmap(&mut self, urid: URID) -> Option<&CStr>

Try to unmap a URID to a URI.

Since mapping URIs to URIDs may not be a surjective function, unmapping may be a partial function: Not every URID is necessarily mapped to a URI. Therefore, this function returns None if the given URID is not mapped.
