Crate beamterm_core 

Stability Policy

beamterm-core’s public API includes types from the following third-party crates:

Crate	Types exposed	Re-exported as
glow	glow::Context in method parameters and RenderContext::gl	beamterm_core::glow
compact_str	CompactString in return types and struct fields	beamterm_core::compact_str

These crates are re-exported so that downstream users can depend on beamterm_core::glow and beamterm_core::compact_str without adding separate dependencies or worrying about version mismatches.

Semver policy: A dependency version bump (e.g. glow 0.17 to 0.18) is only considered a beamterm breaking change if the type signatures used in beamterm’s public API actually change. A version bump that preserves the same type signatures is a compatible update.
