Struct stam::TextResource

impl TextResource

pub fn new(id: impl Into<String>, config: Config) -> Self

Instantiates a new completely empty TextResource

pub fn from_file(filename: &str, config: Config) -> Result<Self, StamError>

Create a new TextResource from file, the text will be loaded into memory entirely

pub fn with_string(self, text: impl Into<String>) -> Self

Sets the text of the TextResource from string, kept in memory entirely The use of Self::from_string() is preferred instead. This method can be dangerous if it modifies any existing text of a resource.

pub fn to_txt_file(&self, filename: &str) -> Result<(), StamError>

Writes a plain text file

pub fn from_string( id: impl Into<String>, text: impl Into<String>, config: Config ) -> Self

Create a new TextResource from string, kept in memory entirely

pub fn known_textselection( &self, offset: &Offset ) -> Result<Option<TextSelectionHandle>, StamError>

Finds a known text selection, as specified by the offset. Known textselections are associated with an annotation. Returns a handle. Use the higher-level method FindText::textselection() instead if you want to return a textselection regardless of whether it’s known or not.

pub fn textselection_by_offset( &self, offset: &Offset ) -> Result<TextSelection, StamError>

Low-level method to get a textselection, if the text selection is known, its’ handle will be set If you don’t care about unbound textselection but only known ones, then use Self::known_textselection() instead.

pub fn textselections_unsorted(&self) -> impl Iterator<Item = &TextSelection>

Low-level method returning an unsorted iterator over all textselections in this resource Use this only if order doesn’t matter for. For a sorted version, use Self::iter() or Self::range() instead.

pub fn textselections_len(&self) -> usize

pub fn range<'a>(&'a self, begin: usize, end: usize) -> TextSelectionIter<'a> ⓘ

Returns a sorted double-ended iterator over a range of all textselections and returns all textselections (in order) that either start or end in this range (depending on the direction you’re iterating in).

pub fn iter<'a>(&'a self) -> TextSelectionIter<'a> ⓘ

Returns a sorted double-ended iterator over all textselections in this resource. For unsorted (slightly more performant), use TextResource::textselections_unsorted() instead.

pub fn positions<'a>( &'a self, mode: PositionMode ) -> Box<dyn Iterator<Item = &'a usize> + 'a>

Returns a sorted iterator over all absolute positions (begin aligned cursors) that are in use. By passing a PositionMode parameter you can specify whether you want only positions where a textselection begins, ends or both.

pub fn positions_in_range<'a>( &'a self, mode: PositionMode, begin: usize, end: usize ) -> Box<dyn Iterator<Item = &'a usize> + 'a>

Returns a sorted iterator over all absolute positions (begin aligned cursors) that are in use within a certain range. By passing a PositionMode parameter you can specify whether you want only positions where a textselection begins, ends or both.

pub fn position(&self, index: usize) -> Option<&PositionIndexItem>

Lookup a position (unicode point) in the PositionIndex. Low-level function. Only works for positions at which a TextSelection starts or ends (non-inclusive), returns None otherwise

pub fn positionindex_len(&self) -> usize

Returns the number of positions in the positionindex

pub fn meminfo(&self) -> usize

Returns a lower-bound estimate of memory usage in bytes

pub fn shrink_to_fit(&mut self)
