Struct Context 

pub struct Context {
    pub variables: HashMap<String, ContextValue>,
    pub globals: HashMap<String, ContextValue>,
    pub buffer_ids: Vec<i64>,
    pub cwd: Option<String>,
    pub metadata: ContextMetadata,
}

Represents the RLM execution context.

This mirrors the Python implementation’s context dict and globals, providing a persistent state across operations.

Examples

use rlm_rs::core::Context;

let mut ctx = Context::new();
ctx.set_variable("key".to_string(), "value".into());
assert!(ctx.get_variable("key").is_some());

Fields

variables: HashMap<String, ContextValue>

Context variables (key-value pairs for current session).

globals: HashMap<String, ContextValue>

Global state dictionary (persisted across sessions).

buffer_ids: Vec<i64>

Active buffer IDs in this context.

cwd: Option<String>

Current working directory path.

metadata: ContextMetadata

Context metadata.

Implementations

impl Context

pub fn new() -> Self

Creates a new empty context with current timestamp.

pub fn set_variable(&mut self, key: String, value: ContextValue)

Sets a context variable.

Arguments

• key - Variable name.
• value - Variable value.

pub fn get_variable(&self, key: &str) -> Option<&ContextValue>

Gets a context variable by key.

Arguments

• key - Variable name to look up.

Returns

Reference to the value if found.

pub fn remove_variable(&mut self, key: &str) -> Option<ContextValue>

Removes a context variable.

Arguments

• key - Variable name to remove.

Returns

The removed value if it existed.

pub fn set_global(&mut self, key: String, value: ContextValue)

Sets a global variable (persisted across sessions).

Arguments

• key - Global variable name.
• value - Global variable value.

pub fn get_global(&self, key: &str) -> Option<&ContextValue>

Gets a global variable by key.

Arguments

• key - Global variable name to look up.

Returns

Reference to the value if found.

pub fn remove_global(&mut self, key: &str) -> Option<ContextValue>

Removes a global variable.

Arguments

• key - Global variable name to remove.

Returns

The removed value if it existed.

pub fn add_buffer(&mut self, buffer_id: i64)

Adds a buffer ID to the active buffers list.

Arguments

• buffer_id - ID of the buffer to add.

pub fn remove_buffer(&mut self, buffer_id: i64) -> bool

Removes a buffer ID from the active buffers list.

Arguments

• buffer_id - ID of the buffer to remove.

Returns

true if the buffer was removed, false if not found.

pub fn reset(&mut self)

Resets the context to empty state, preserving metadata.

pub fn variable_count(&self) -> usize

Returns the number of variables in the context.

pub fn global_count(&self) -> usize

Returns the number of globals in the context.

pub const fn buffer_count(&self) -> usize

Returns the number of active buffers.

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Context

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

Formats the value using the given formatter.

impl Default for Context

fn default() -> Context

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Context

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Context

fn eq(&self, other: &Context) -> 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 Serialize for Context

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
