pub struct ScriptTag { /* private fields */ }

PEP 723 metadata as parsed from a script comment block.

See: https://peps.python.org/pep-0723/

Vendored from: https://github.com/astral-sh/uv/blob/debe67ffdb0cd7835734100e909b2d8f79613743/crates/uv-scripts/src/lib.rs#L283

Implementations

impl ScriptTag

pub fn parse(contents: &[u8]) -> Option<ScriptTag>

Given the contents of a Python file, extract the script metadata block with leading comment hashes removed, any preceding shebang or content (prelude), and the remaining Python script.

Given the following input string representing the contents of a Python script:

#!/usr/bin/env python3
# /// script
# requires-python = '>=3.11'
# dependencies = [
#   'requests<3',
#   'rich',
# ]
# ///

import requests

print("Hello, World!")

This function would return:

• Preamble: #!/usr/bin/env python3\n
• Metadata: requires-python = '>=3.11'\ndependencies = [\n 'requests<3',\n 'rich',\n]
• Postlude: import requests\n\nprint("Hello, World!")\n

Trait Implementations

impl Clone for ScriptTag

fn clone(&self) -> ScriptTag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScriptTag

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

Formats the value using the given formatter.

impl PartialEq for ScriptTag

fn eq(&self, other: &ScriptTag) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
