Trait TlvData 

pub trait TlvData<'a>: TryFrom<&'a [u32]>
where
    for<'b> Vec<u32>: From<&'b Self>,
{
    // Required methods
    fn value_type(&self) -> u32;
    fn value_length(&self) -> usize;
    fn value(&self) -> Vec<u32>;
}

The trait for common methods to data of TLV (Type-Length-Value) in ALSA control interface. The TryFrom supertrait should be implemented to parse the array of u32 elements and it can return TlvDecodeError at failure. The trait boundary to Vec::::From(&Self) should be implemented as well to build the array of u32 element.

Required Methods

fn value_type(&self) -> u32

Return the value of type field. It should come from UAPI of Linux kernel.

fn value_length(&self) -> usize

Return the length of value field. It should be in byte unit and multiples of 4 as result.

fn value(&self) -> Vec<u32>

Generate vector with u32 element for raw data.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
