Struct LV2_URID_Unmap 

#[repr(C)]
pub struct LV2_URID_Unmap {
    pub handle: LV2_URID_Unmap_Handle,

}

URI Unmap Feature (LV2_URID__unmap)

Fields

handle: LV2_URID_Unmap_Handle

Opaque pointer to host data.

This MUST be passed to unmap() whenever it is called. Otherwise, it must not be interpreted in any way.

unmap: Option<unsafe extern "C" fn(handle: LV2_URID_Unmap_Handle, urid: LV2_URID) -> *const c_char>

Get the URI for a previously mapped numeric ID.

Returns NULL if urid is not yet mapped. Otherwise, the corresponding URI is returned in a canonical form. This MAY not be the exact same string that was originally passed to LV2_URID_Map::map(), but it MUST be an identical URI according to the URI syntax specification (RFC3986). A non-NULL return for a given urid will always be the same for the life of the plugin. Plugins that intend to perform string comparison on unmapped URIs SHOULD first canonicalise URI strings with a call to map_uri() followed by a call to unmap_uri().

@param handle Must be the callback_data member of this struct. @param urid The ID to be mapped back to the URI string.
