Struct lv2rs_urid::Map

#[repr(C)]
pub struct Map {
    pub handle: MapHandle,
    pub map: extern "C" fn(handle: MapHandle, uri: *const c_char) -> URID,
}

Struct for mapping URIs to URIDs.

Fields

handle: MapHandle

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

map: extern "C" fn(handle: MapHandle, uri: *const c_char) -> URID

Function that maps a URI to a URID.

Methods

impl Map

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

Try to find the mapping feature in the features map.

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

pub fn map<'a, S>(&mut self, uri: S) -> URID where
    &'a CStr: From<S>, 

Map a URI to a URID.

If the host is properly implemented, this should be an injective function: Every URI should be mapped to a unique URID.
