Struct MultiPagedRangeBuf 

pub struct MultiPagedRangeBuf { /* private fields */ }

Implementations

impl MultiPagedRangeBuf

pub fn from_range_buffer(count: usize, buf: Vec<u64>) -> Result<Self, Error>

pub fn new() -> Self

pub fn iter(&self) -> MultiPagedRangeIter<'_>

pub fn range_count(&self) -> usize

pub fn first(&self) -> Option<PagedRange<'_>>

pub fn contiguous_aligned(&self) -> Option<PagedRange<'_>>

Validates that this multi range consists of exactly one range that is page aligned. Returns that range.

pub fn range_buffer(&self) -> &[u64]

pub fn clear(&mut self)

Clears the buffer and resets the range count to zero.

pub fn push_range(&mut self, range: PagedRange<'_>)

Appends a new paged range to the buffer.

pub fn try_extend_with<E>( &mut self, len: usize, count: usize, f: impl FnOnce(&mut [u64]) -> Result<(), E>, ) -> Result<Result<(), Error>, E>

Attempts to extend the buffer by count ranges, requiring len u64 entries in total. f is called to fill in the newly allocated buffer space.

If f returns an error, the buffer is restored to its previous state and the error is propagated. If f returns Ok(()), the newly added ranges are validated; if validation fails, the buffer is restored and the validation error is returned inside Ok(Err(_)).
