Struct StackTraceLine 

pub struct StackTraceLine { /* private fields */ }

Stack trace line parsed from a [LuaError].

Implementations

impl StackTraceLine

pub fn source(&self) -> StackTraceSource

Returns the source of the stack trace line.

pub fn path(&self) -> Option<&str>

Returns the path, if it exists.

pub fn line_number(&self) -> Option<usize>

Returns the line number, if it exists.

pub fn function_name(&self) -> Option<&str>

Returns the function name, if it exists.

pub const fn is_empty(&self) -> bool

Returns true if the stack trace line contains no “useful” information, false otherwise.

Useful information is determined as one of:

• A path
• A line number
• A function name
