Struct ExecutionContext 

pub struct ExecutionContext {
    pub bindings: HashMap<String, ToolResult>,
    pub execution_log: Vec<ExecutionStep>,
    pub variables: Map<String, Value>,
    pub last_result: Option<ToolResult>,
    /* private fields */
}

Context for tool execution, carrying variables and state

Fields

bindings: HashMap<String, ToolResult>

Variable bindings (for new DSL)

execution_log: Vec<ExecutionStep>

Execution history for debugging

variables: Map<String, Value>

Variables for old API compatibility

last_result: Option<ToolResult>

Last result for old API compatibility

Implementations

impl ExecutionContext

pub fn new() -> Self

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

Get a variable (old API)

pub fn with_variable(self, key: impl Into<String>, value: Value) -> Self

With variable builder pattern (old API)

pub fn with_last_result(self, result: ToolResult) -> Self

With last result (old API)

pub fn bind(&mut self, name: String, value: ToolResult)
