Struct CssVariableManager 

pub struct CssVariableManager { /* private fields */ }

Manages CSS variables across the workspace

Implementations

impl CssVariableManager

pub fn new(config: Config) -> Self

pub async fn accept_document_version(&self, uri: &Uri, version: i64) -> bool

Record a document version if it is newer than the last accepted version.

Returning false for equal or older versions lets LSP notification handlers discard duplicate and stale changes before mutating their text snapshots.

pub async fn clear_document_version(&self, uri: &Uri)

Forget the version associated with a document that is no longer open.

pub async fn get_document_version(&self, uri: &Uri) -> Option<i64>

Return the latest accepted version for an open document.

pub async fn add_variable(&self, variable: CssVariable) -> Result<(), String>

Add a variable definition

pub async fn add_variables( &self, variables: Vec<CssVariable>, ) -> Result<(), String>

Add variable definitions atomically under one variables lock.

pub async fn replace_document_variables( &self, uri: &Uri, variables: Vec<CssVariable>, ) -> Result<(), String>

Atomically replace all variable definitions owned by one document.

pub async fn replace_document_analysis( &self, uri: &Uri, variables: Vec<CssVariable>, usages: Vec<CssVariableUsage>, ) -> Result<(), String>

Atomically replace variable definitions and usages owned by one document.

pub async fn replace_document_analysis_at_version( &self, uri: &Uri, version: i64, variables: Vec<CssVariable>, usages: Vec<CssVariableUsage>, ) -> Result<bool, String>

Replace one document’s analysis only if its version is still current.

The version lock is held for the complete tracked/variables/usages replacement, so a newer accepted version cannot make this parse obsolete between the check and the commit.

pub async fn add_usage(&self, usage: CssVariableUsage)

Add a variable usage

pub async fn add_literal_color(&self, occurrence: LiteralColorOccurrence)

Add a literal color occurrence

pub async fn get_variables(&self, name: &str) -> Vec<CssVariable>

Get all definitions of a variable

pub async fn get_usages(&self, name: &str) -> Vec<CssVariableUsage>

Get all usages of a variable

pub async fn resolve_variable_color(&self, name: &str) -> Option<Color>

Resolve a variable name to a color using cascade ordering and var() chains.

pub async fn resolve_variable_color_key( &self, name: &str, ) -> Option<NormalizedColorKey>

Resolve a variable name to a normalized color key using cascade ordering and var() chains.

pub async fn get_all_variables(&self) -> Vec<CssVariable>

Get all variables (for completion)

pub async fn get_references( &self, name: &str, ) -> (Vec<CssVariable>, Vec<CssVariableUsage>)

Get all references (definitions + usages) for a variable

pub async fn get_document_literal_colors( &self, uri: &Uri, ) -> Vec<LiteralColorOccurrence>

Get literal color occurrences in a specific document.

pub async fn get_literal_colors_at_position( &self, uri: &Uri, position: Position, ) -> Vec<LiteralColorOccurrence>

Get literal color occurrences at a specific position (O(1) line lookup + O(k) scan).

pub async fn get_variables_by_color_key( &self, key: &NormalizedColorKey, ) -> Vec<CssVariable>

Get all variables whose resolved color exactly matches the normalized color key.

pub async fn get_document_resolved_color_keys( &self, uri: &Uri, ) -> HashSet<NormalizedColorKey>

Get the set of resolved variable colors currently defined in a specific document.

pub async fn remove_document(&self, uri: &Uri)

Remove all data for a document

pub async fn remove_documents(&self, uris: &HashSet<Uri>)

Remove all data for a set of documents.

pub async fn get_document_uris(&self) -> HashSet<Uri>

Get every document URI currently represented in manager state.

pub async fn get_document_variables(&self, uri: &Uri) -> Vec<CssVariable>

Get all variables defined in a specific document

pub async fn get_document_variable_names(&self, uri: &Uri) -> HashSet<String>

Get the set of variable names defined in a specific document

pub async fn get_document_usages(&self, uri: &Uri) -> Vec<CssVariableUsage>

Get all variable usages in a specific document

pub async fn set_dom_tree(&self, uri: Uri, dom_tree: DomTree)

Set DOM tree for a document

pub async fn get_dom_tree(&self, uri: &Uri) -> Option<DomTree>

Get DOM tree for a document

pub async fn get_config(&self) -> Config

Get current configuration

pub async fn set_config(&self, config: Config)

Replace the current configuration.

pub async fn rebuild_color_index(&self)

Rebuild the normalized-color -> variable-name lookup from current workspace state.

Trait Implementations

impl Clone for CssVariableManager

fn clone(&self) -> CssVariableManager

Returns a duplicate of the value.

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

Performs copy-assignment from source.
