Struct agde::utils::Offsets

pub struct Offsets { /* private fields */ }

The offsets previous events cause on any future events which have not taken the previous ones into account.

Implementations

impl Offsets

pub fn new() -> Self

Create a new set of offsets for some old differences.

pub fn add_diff(&mut self, diff: &Difference, len_diff: isize)

Add another diff to us.

len_diff is the difference in length before and after applying diff to your data, like after - before. Consider using utils::sub_usize.

pub fn apply_single(&self, diff: &mut Difference)

Apply these offsets to a single diff.

Use Self::apply for a more convenient function.

pub fn apply<'a>(self, events: impl Iterator<Item = &'a mut Event>)

Apply the offsets on events to adjust them to the events that have since changed (Self::add_diff).

Will set all the Events’ block_sizes to 1.

events should be an iterator over the Events with the relevant Event::resource.

pub fn transform_index(&self, index: usize) -> usize

Returns where index is after the diffs we are tracking are applied.

This is provided on a best-effort basis, just like the rest of this struct.

Trait Implementations

impl Debug for Offsets

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

Formats the value using the given formatter.

impl Default for Offsets

fn default() -> Self

Returns the “default value” for a type.
