Struct SaturatedSlice 

pub struct SaturatedSlice { /* private fields */ }

A saturated slice with values ranging in [isize::MIN, isize::MAX]. Used for sliceable sequences that require indices in the aforementioned range.

Invokes __index__ on the PySliceRef during construction so as to separate the transformation from PyObject into isize and the adjusting of the slice to a given sequence length. The reason this is important is due to the fact that an objects __index__ might get a lock on the sequence and cause a deadlock.

Implementations

impl SaturatedSlice

pub const fn from_parts(start: isize, stop: isize, step: isize) -> Self

pub const fn start(&self) -> isize

pub const fn stop(&self) -> isize

pub const fn step(&self) -> isize

pub fn with_slice(slice: &Py<PySlice>, vm: &VirtualMachine) -> PyResult<Self>

pub fn adjust_indices(&self, len: usize) -> (Range<usize>, isize, usize)

Convert for usage in indexing the underlying rust collections. Called after index has been called on the Slice which might mutate the collection.

pub fn adjust_indices_start(&self, len: usize) -> (isize, usize)

The index the slice begins at, clamped into 0..=len for a positive step and into -1..=len-1 for a negative one, together with its length.

Unlike Self::adjust_indices this stays meaningful for an empty slice, where it is still the position a strided view moves to.

pub fn iter(&self, len: usize) -> SaturatedSliceIter
