Struct TestRange

pub struct TestRange {
    pub id: u32,
    pub len: u32,
    pub is_activated: bool,
}

This is a simple span object for testing.

Fields

id: u32

len: u32

is_activated: bool

Trait Implementations

impl Clone for TestRange

fn clone(&self) -> TestRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ContentLength for TestRange

fn content_len(&self) -> usize

User specific content length. Used by content-tree for character counts.

fn content_len_at_offset(&self, offset: usize) -> usize

fn offset_len_at_content(&self, content: usize) -> usize

impl Debug for TestRange

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

Formats the value using the given formatter.

impl Default for TestRange

fn default() -> Self

Returns the “default value” for a type.

impl HasLength for TestRange

fn len(&self) -> usize

The number of child items in the entry. This is indexed with the size used in truncate.

fn is_empty(&self) -> bool

impl MergableSpan for TestRange

fn can_append(&self, other: &Self) -> bool

See if the other item can be appended to self. can_append will always be called immediately before append.

fn append(&mut self, other: Self)

Merge the passed item into self. Essentially, self = self + other.

fn prepend(&mut self, other: Self)

Append an item at the start of this item. self = other + self.

impl PartialEq for TestRange

fn eq(&self, other: &TestRange) -> 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 Searchable for TestRange

type Item = (u32, bool)

fn get_offset(&self, loc: Self::Item) -> Option<usize>

Checks if the entry contains the specified item. If it does, returns the offset into the item.

fn at_offset(&self, offset: usize) -> Self::Item

impl SplitableSpanHelpers for TestRange

fn truncate_h(&mut self, at: usize) -> Self

Split the entry, returning the part of the entry which was jettisoned. After truncating at pos, self.len() == pos and the returned value contains the rest of the items.

fn truncate_keeping_right_h(&mut self, at: usize) -> Self

The inverse of truncate. This method mutably truncates an item, keeping all content from at..item.len() and returning the item range from 0..at.

fn split(self, at: usize) -> (Self, Self)

impl Toggleable for TestRange

fn is_activated(&self) -> bool

fn mark_activated(&mut self)

fn mark_deactivated(&mut self)

fn is_deactivated(&self) -> bool

impl Copy for TestRange

impl Eq for TestRange
