Module asset 

Asset selection for the running host.

Grammar

The default asset-name pattern is {name}-{version}-{target}{ext}. Tool authors override via rtb_app::metadata::ToolMetadata::update_asset_pattern.

Placeholders:

Placeholder	Value
{name}	rtb_app::metadata::ToolMetadata::name
{version}	Release tag with any leading v stripped
{target}	Rust host triple (e.g. x86_64-unknown-linux-gnu)
{os}	linux, macos, windows
{arch}	x86_64, aarch64
{ext}	.tar.gz on Unix / .zip on Windows

All occurrences of each placeholder are replaced. Unknown placeholders pass through verbatim — useful when a tool author embeds release-pipeline-specific substitutions we haven’t anticipated yet.

Constants

DEFAULT_PATTERN

Default pattern — matches the release-pipeline conventions we recommend to tool authors.

Functions

host_substitutions

Return (os, arch, target_triple, ext) for the running binary.

pick_asset

Pick the asset on release whose name matches expected.

pick_signature

Find the signature file for asset on release. Preference: .minisig over .sig (minisign format carries more context when things go wrong). Returns None if neither is present.

render_pattern

Render the asset pattern with host + release substitutions.
