Struct Slice 

pub struct Slice<T> { /* private fields */ }

Relative range within a compiled query segment.

Used for variable-length data (successors, effects, negated fields, type members). The slice references elements by index into the corresponding segment array.

Layout: 8 bytes (4 + 2 + 2), align 4.

Implementations

impl<T> Slice<T>

pub const fn new(start_index: u32, len: u16) -> Self

Creates a new slice.

pub const fn empty() -> Self

Creates an empty slice.

pub fn start_index(&self) -> u32

Returns the start index (element index, not byte offset).

pub fn len(&self) -> u16

Returns the number of elements.

pub fn is_empty(&self) -> bool

Returns true if the slice is empty.

pub const fn from_inner_type(type_id: u16) -> Self

Creates a slice encoding an inner type ID (for wrapper TypeDef). The start_index stores the TypeId as u32, len is 0.

Trait Implementations

impl<T: Clone> Clone for Slice<T>

fn clone(&self) -> Slice<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Slice<T>

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

Formats the value using the given formatter.

impl<T> Default for Slice<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T> PartialEq for Slice<T>

fn eq(&self, other: &Self) -> 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.
