Struct FunctionHeader 

pub struct FunctionHeader<'ast> {
    pub span: Span,
    pub name: Option<Ident>,
    pub parameters: ParameterList<'ast>,
    pub visibility: Option<Spanned<Visibility>>,
    pub state_mutability: Option<Spanned<StateMutability>>,
    pub modifiers: BoxSlice<'ast, Modifier<'ast>>,
    pub virtual_: Option<Span>,
    pub override_: Option<Override<'ast>>,
    pub returns: Option<ParameterList<'ast>>,
}

A function header: function helloWorld() external pure returns(string memory).

Fields

span: Span

The span of the function header.

name: Option<Ident>

The name of the function. Only None if this is a constructor, fallback, or receive function.

parameters: ParameterList<'ast>

The parameters of the function.

visibility: Option<Spanned<Visibility>>

The visibility keyword.

state_mutability: Option<Spanned<StateMutability>>

The state mutability.

modifiers: BoxSlice<'ast, Modifier<'ast>>

The function modifiers.

virtual_: Option<Span>

The span of the virtual keyword.

override_: Option<Override<'ast>>

The override keyword.

returns: Option<ParameterList<'ast>>

The returns parameter list.

If Some, it’s always non-empty.

Implementations

impl<'ast> FunctionHeader<'ast>

pub fn visibility(&self) -> Option<Visibility>

pub fn state_mutability(&self) -> StateMutability

Trait Implementations

impl<'ast> Debug for FunctionHeader<'ast>

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

Formats the value using the given formatter.

impl<'ast> Default for FunctionHeader<'ast>

fn default() -> FunctionHeader<'ast>

Returns the “default value” for a type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
