Struct rodio::source::SamplesConverter
[−]
[src]
pub struct SamplesConverter<I, D> where
I: Source,
I::Item: Sample,
D: Sample, { /* fields omitted */ }
An iterator that reads from a Source
and converts the samples to a specific rate and
channels count.
It implements Source
as well, but all the data is guaranteed to be in a single frame whose
channels and samples rate have been passed to new
.
