Struct ChunkRangesSeq

pub struct ChunkRangesSeq(/* private fields */);

Implementations

impl ChunkRangesSeq

pub const fn empty() -> Self

pub fn root() -> Self

Request just the first blob.

pub fn all() -> Self

A ChunkRangesSeq containing all chunks from all blobs.

ChunkRangesSeq::iter, will return a full range forever.

pub fn verified_size() -> Self

A ChunkRangesSeq getting the verified size for the first blob.

pub fn verified_child_sizes() -> Self

A ChunkRangesSeq getting the entire first blob and verified sizes for all others.

pub fn is_empty(&self) -> bool

Checks if this ChunkRangesSeq does not select any chunks in the blob.

pub fn is_all(&self) -> bool

Checks if this ChunkRangesSeq selects all chunks in the blob.

pub fn as_single(&self) -> Option<(u64, &ChunkRanges)>

If this range seq describes a range for a single item, returns the offset and range spec for that item

pub fn is_blob(&self) -> bool

pub fn from_ranges_infinite( ranges: impl IntoIterator<Item = ChunkRanges>, ) -> Self

Convenience function to create a ChunkRangesSeq from an iterator of chunk ranges. If the last element is non-empty, it will be repeated forever.

pub fn from_ranges(ranges: impl IntoIterator<Item = ChunkRanges>) -> Self

Convenience function to create a ChunkRangesSeq from an iterator of chunk ranges. If the last element is non-empty, an empty range will be added immediately after it to terminate the sequence.

pub fn iter_non_empty_infinite(&self) -> NonEmptyRequestRangeSpecIter<'_>

An iterator over blobs in the sequence with a non-empty range spec.

This iterator will only yield items for blobs which have at least one chunk selected.

This iterator is infinite if the ChunkRangesSeq ends on a non-empty ChunkRanges, that is all further blobs have selected chunks spans.

pub fn is_infinite(&self) -> bool

True if this range spec sequence repeats the last range spec forever.

pub fn iter_infinite(&self) -> ChunkRangesSeqIterInfinite<'_>

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

Trait Implementations

impl Clone for ChunkRangesSeq

fn clone(&self) -> ChunkRangesSeq

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ChunkRangesSeq

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ChunkRangesSeq

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ChunkRangesSeq

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Index<u64> for ChunkRangesSeq

type Output = RangeSet<[ChunkNum; 2]>

The returned type after indexing.

fn index(&self, index: u64) -> &Self::Output

Performs the indexing (container[index]) operation.

impl PartialEq for ChunkRangesSeq

fn eq(&self, other: &ChunkRangesSeq) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ChunkRangesSeq

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
