Struct midly::EventBytemapIter
source · pub struct EventBytemapIter<'a> { /* private fields */ }
Expand description
An iterator over the events of a single track that keeps track of the raw bytes that make up
each event.
Created by the EventIter::bytemapped
method.
This iterator is lazy, it parses events as it goes, and therefore produces
Result<(&[u8], TrackEvent)>>
rather than just (&[u8], TrackEvent)
.
This type is always available, even in no_std
environments.
Implementations§
source§impl<'a> EventBytemapIter<'a>
impl<'a> EventBytemapIter<'a>
sourcepub fn new(raw: &[u8]) -> EventBytemapIter<'_> ⓘ
pub fn new(raw: &[u8]) -> EventBytemapIter<'_> ⓘ
Create an event iterator from raw track bytes.
It can be hard to obtain raw track bytes.
Usually these raw track bytes are obtained from the unread
method on an
event iterator.
sourcepub fn running_status(&self) -> Option<u8>
pub fn running_status(&self) -> Option<u8>
Get the current running status of the track.
sourcepub fn running_status_mut(&mut self) -> &mut Option<u8>
pub fn running_status_mut(&mut self) -> &mut Option<u8>
Modify the current running status of the track.
sourcepub fn not_bytemapped(self) -> EventIter<'a> ⓘ
pub fn not_bytemapped(self) -> EventIter<'a> ⓘ
Stop collecting bytemap information for any remaining events.
sourcepub fn into_vec(self) -> Result<Vec<(&'a [u8], TrackEvent<'a>)>>
pub fn into_vec(self) -> Result<Vec<(&'a [u8], TrackEvent<'a>)>>
Collects the remaining unparsed events into a Vec<(&[u8], TrackEvent)>
.
This function is a smarter version of Iterator::collect
, as it guesses allocations and
is usually optimized better than its naive counterpart.
This function is only available with the alloc
feature enabled.
