Struct FunctionCall 

pub struct FunctionCall {
    pub callee: String,
    pub line: usize,
    pub end_line: usize,
    pub snippet: String,
}

A function or method call-site in a Rust file.

Stores one example per unique callee name (deduplication happens in the parser). The snippet captures a window around the call so that MCP clients can show real usage patterns without additional disk I/O at query time.

Snippet layout

[2 lines of context before the opening line]
[all lines of the call expression — may span many lines for multi-arg calls]
[4 lines of context after the closing line]

Hard cap: 30 lines total. Lines are taken from the raw source file and include the original indentation.

Fields

callee: String

Full callee name as written in source, e.g. "scan_project", "Arc::new", "db.execute", "tracing::info".

line: usize

1-indexed line of the opening of the call expression (function name position).

end_line: usize

1-indexed line of the closing parenthesis of the call expression. Equals line for single-line calls.

snippet: String

Multi-line snippet centered on the call site (see type-level docs). Empty string if source was unavailable at parse time.

Trait Implementations

impl Clone for FunctionCall

fn clone(&self) -> FunctionCall

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionCall

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FunctionCall

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for FunctionCall

impl PartialEq for FunctionCall

fn eq(&self, other: &FunctionCall) -> 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 FunctionCall

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
