Language-agnostic function body

This enum wraps language-specific AST representations of function bodies, allowing the rest of the codebase to work with different languages uniformly.

Variants

ECMAScript(BlockStmt)

ECMAScript (TypeScript/JavaScript) function body

Wraps SWC’s BlockStmt which represents the body of a function, method, arrow function, etc.

Go

Go function body

Contains the tree-sitter node ID for the block and the source code. We store the source because tree-sitter nodes are tied to the tree lifetime.

Fields

body_node: usize

The tree-sitter node ID for the function body block

source: String

The source code (needed to reconstruct the tree)

Java

Java function body

Contains the tree-sitter node ID for the block and the source code. We store the source because tree-sitter nodes are tied to the tree lifetime.

Fields

body_node: usize

The tree-sitter node ID for the function body block

source: String

The source code (needed to reconstruct the tree)

Python

Python function body

Contains the tree-sitter node ID for the block and the source code. We store the source because tree-sitter nodes are tied to the tree lifetime.

Fields

body_node: usize

The tree-sitter node ID for the function body block

source: String

The source code (needed to reconstruct the tree)

Rust

Rust function body

Contains the source code for the function body. We re-parse on demand using syn when building CFG or extracting metrics.

Fields

source: String

The source code for the entire function (signature + body)

CSharp

C# function body

Contains the tree-sitter node ID for the block and the source code.

Fields

body_node: usize

The tree-sitter node ID for the function body block

source: String

The source code (needed to reconstruct the tree)

C

C function body

Contains the tree-sitter node ID for the compound_statement and the source code.

Fields

body_node: usize

The tree-sitter node ID for the function body compound_statement

source: String

The source code (needed to reconstruct the tree)

Implementations

impl FunctionBody

pub fn ecmascript(block: BlockStmt) -> Self

Create an ECMAScript function body

pub fn is_ecmascript(&self) -> bool

Check if this is an ECMAScript function body

pub fn is_go(&self) -> bool

Check if this is a Go function body

pub fn is_java(&self) -> bool

Check if this is a Java function body

pub fn is_python(&self) -> bool

Check if this is a Python function body

pub fn is_rust(&self) -> bool

Check if this is a Rust function body

pub fn is_csharp(&self) -> bool

Check if this is a C# function body

pub fn is_c(&self) -> bool

Check if this is a C function body

pub fn as_ecmascript(&self) -> &BlockStmt

Get the ECMAScript body, if this is one

Panics

Panics if this is not an ECMAScript body. Use is_ecmascript() to check first, or use pattern matching instead.

pub fn as_ecmascript_mut(&mut self) -> &mut BlockStmt

Get a mutable reference to the ECMAScript body, if this is one

Panics

Panics if this is not an ECMAScript body.

pub fn as_go(&self) -> (usize, &str)

Get the Go body node ID and source, if this is a Go function

Panics

Panics if this is not a Go body. Use is_go() to check first.

pub fn as_java(&self) -> (usize, &str)

Get the Java body node ID and source, if this is a Java function

Panics

Panics if this is not a Java body. Use is_java() to check first.

pub fn as_python(&self) -> (usize, &str)

Get the Python body node ID and source, if this is a Python function

Panics

Panics if this is not a Python body. Use is_python() to check first.

pub fn as_rust(&self) -> &str

Get the Rust source, if this is a Rust function

Panics

Panics if this is not a Rust body. Use is_rust() to check first.

pub fn as_csharp(&self) -> (usize, &str)

Get the C# body node ID and source, if this is a C# function

Panics

Panics if this is not a C# body. Use is_csharp() to check first.

pub fn as_c(&self) -> (usize, &str)

Get the C body node ID and source, if this is a C function

Panics

Panics if this is not a C body. Use is_c() to check first.

Trait Implementations
