[−][src]Struct lv2_state::StatePropertyReader

pub struct StatePropertyReader<'a> { /* fields omitted */ }

Reading handle for properties.

This handle contains the type and the data of a property retrieved from the RetrieveHandle.

Methods

impl<'a> StatePropertyReader<'a>[src]

pub fn new(type_: URID, body: Space<'a>) -> Self[src]

Create a new reading handle with the given type and data.

pub fn type_(&self) -> URID[src]

Return the type of the property.

pub fn body(&self) -> Space[src]

Return the data of the property.

pub fn read<A: Atom<'a, 'a>>(
    &self,
    urid: URID<A>,
    parameter: A::ReadParameter
) -> Result<A::ReadHandle, StateErr>[src]

Try to interpret the property as an atom.

This works like any atom reader: You pass the URID of the atom type as well as the type-specific argument, and if the desired type is the actual type of the data, a read handle is returned.

If the desired and actual data types don't match, Err(StateErr::BadType) is returned.
