Struct SourceRange 

pub struct SourceRange {
    pub filename: String,
    pub start: u32,
    pub end: u32,
}

The source range of the expression that suspended execution, carried by every suspension.

start and end are UTF-8 byte offsets into the named source, end exclusive: slice the source’s bytes (in Python, source.encode()[start:end]) rather than indexing the string. A peer that sends no position reads as Self::unknown.

Fields

filename: String

The source the range indexes, named as a traceback frame names it: an in-process one-shot run’s script name, <python-input-N> for a feed, <string> in eval() / exec().

start: u32

Byte offset where the expression starts.

end: u32

Byte offset where the expression ends (exclusive).

Implementations

impl SourceRange

pub const MAX_FILENAME_LEN: usize = 256

Longest filename a range carries, in bytes, so a peer cannot make hosts copy a huge name.

pub fn new(filename: &str, start: u32, end: u32) -> Self

Builds a range, cutting filename on a char boundary.

pub fn unknown() -> Self

The range a host reports when its peer sent no position: an empty filename and an empty range at offset zero.
