Struct ContextManager 

pub struct ContextManager { /* private fields */ }

Context manager that caches computed contexts

Uses ArcSwap for lock-free reads during rendering.

Implementations

impl ContextManager

pub fn new() -> Self

Create a new context manager

pub fn cursor_changed(&self, buffer_id: usize, line: u32, col: u32) -> bool

Check if cursor position changed

Returns true if position differs from last known position, or if never processed.

Panics

Panics if the internal lock is poisoned.

pub fn update_cursor(&self, buffer_id: usize, line: u32, col: u32)

Update last cursor position

Panics

Panics if the internal lock is poisoned.

pub fn viewport_changed(&self, buffer_id: usize, top_line: u32) -> bool

Check if viewport top line changed

Returns true if position differs from last known position, or if never processed.

Panics

Panics if the internal lock is poisoned.

pub fn update_viewport(&self, buffer_id: usize, top_line: u32)

Update last viewport position

Panics

Panics if the internal lock is poisoned.

pub fn set_cursor_context(&self, context: CachedContext)

Store cursor context

pub fn get_cursor_context(&self) -> Arc<Option<CachedContext>>

Get cursor context (lock-free read)

pub fn set_viewport_context(&self, context: CachedContext)

Store viewport context

pub fn get_viewport_context(&self) -> Arc<Option<CachedContext>>

Get viewport context (lock-free read)

pub fn invalidate_buffer(&self, buffer_id: usize)

Invalidate cache for a buffer (called on BufferModified)

Panics

Panics if the internal lock is poisoned.

pub fn buffer_version(&self, buffer_id: usize) -> u64

Get current buffer version (for cache validation)

Panics

Panics if the internal lock is poisoned.

Trait Implementations

impl Default for ContextManager

fn default() -> Self

Returns the “default value” for a type.
