Or zero

Negative

Fields

offset_from_end: usize

len: usize

Implementations

impl Slice

pub fn len(&self) -> usize

pub fn len_mut(&mut self) -> &mut usize

pub fn positive_offset(&self) -> usize

Returns the offset of a positive slice.

Panics

Panics if self is Slice::Negative

pub fn end_position(&self) -> usize

Returns the end position of the slice (offset + len).

Panics

Panics if self is negative.

pub fn offsetted(self, position: usize) -> Self

Returns the equivalent slice to apply from an offsetted position.

Panics

Panics if self is negative.

pub fn restrict_to_bounds(self, n_rows: usize) -> Self

Restricts the bounds of the slice to within a number of rows. Negative slices will also be translated to the positive equivalent.

Trait Implementations

impl Clone for Slice

fn clone(&self) -> Slice

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Slice

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Slice

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<(i64, usize)> for Slice

fn from((offset, len): (i64, usize)) -> Self

Converts to this type from the input type.

impl From<(usize, usize)> for Slice

fn from((offset, len): (usize, usize)) -> Self

Converts to this type from the input type.

impl From<Slice> for (i128, i128)

fn from(value: Slice) -> Self

Converts to this type from the input type.

impl From<Slice> for Range<usize>

fn from(value: Slice) -> Self

Converts to this type from the input type.

impl Hash for Slice

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 JsonSchema for Slice

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for Slice

fn eq(&self, other: &Slice) -> 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 Slice

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<Slice> for (i64, usize)

type Error = TryFromIntError

The type returned in the event of a conversion error.

fn try_from(value: Slice) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Slice

impl StructuralPartialEq for Slice
