Implementations

impl BlockStmtOrExpr

pub const fn is_block_stmt(&self) -> bool

Returns true if self is of variant BlockStmt.

pub fn as_block_stmt(&self) -> Option<&BlockStmt>

Returns Some if self is a reference of variant BlockStmt, and None otherwise.

pub fn as_mut_block_stmt(&mut self) -> Option<&mut BlockStmt>

Returns Some if self is a mutable reference of variant BlockStmt, and None otherwise.

pub fn expect_block_stmt(self) -> BlockStmt

where Self: Debug,

Unwraps the value, yielding the content of BlockStmt.

Panics

Panics if the value is not BlockStmt, with a panic message including the content of self.

pub fn block_stmt(self) -> Option<BlockStmt>

Returns Some if self is of variant BlockStmt, and None otherwise.

pub const fn is_expr(&self) -> bool

Returns true if self is of variant Expr.

pub fn as_expr(&self) -> Option<&Box<Expr>>

Returns Some if self is a reference of variant Expr, and None otherwise.

pub fn as_mut_expr(&mut self) -> Option<&mut Box<Expr>>

Returns Some if self is a mutable reference of variant Expr, and None otherwise.

pub fn expect_expr(self) -> Box<Expr>

where Self: Debug,

Unwraps the value, yielding the content of Expr.

Panics

Panics if the value is not Expr, with a panic message including the content of self.

pub fn expr(self) -> Option<Box<Expr>>

Returns Some if self is of variant Expr, and None otherwise.

Trait Implementations

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockStmtOrExpr

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

Formats the value using the given formatter.
