[][src]Struct artichoke_backend::state::parser::Context

pub struct Context { /* fields omitted */ }

Context is used to manipulate the current filename on the parser.

Parser State maintains a stack of Contexts and eval uses the Context stack to set the __FILE__ magic constant.


impl Context[src]

pub fn new<T>(filename: T) -> Option<Self> where
    T: Into<Cow<'static, [u8]>>, 

Create a new Context.

pub unsafe fn new_unchecked<T>(filename: T) -> Self where
    T: Into<Cow<'static, [u8]>>, 

Create a new Context without checking for NUL bytes in the filename.


filename must not contain any NUL bytes. filename must not contain a trailing NUL.

#[must_use]pub fn root() -> Self[src]

Create a root, or default, Context.

The root context sets the __FILE__ magic constant to "(eval)".

#[must_use]pub fn filename(&self) -> &[u8][src]

Filename of this Context.

#[must_use]pub fn filename_as_c_str(&self) -> &CStr[src]

FFI-safe NUL-terminated C String of this Context.

This CStr is valid as long as this Context is not dropped.
