Module GlobPattern 

Glob pattern extraction helpers for WorkspaceProvider::FindFiles calls.

VS Code passes glob patterns in several shapes depending on the caller:

• Bare string: "**/*.rs"
• RelativePattern object: { base, pattern } or { baseUri, pattern }
• Legacy serialised form: { value: "**/*.rs" }

These helpers normalise all shapes to a String and extract the optional base directory for bounded walks.

Functions

ExtractGlobPattern

Extract a glob string from any shape the caller can supply:

ExtractRelativeBase

Extract a base directory from a RelativePattern-shaped value. VS Code’s RelativePattern carries { base, pattern } or { baseUri, pattern }. When present, the file walk is restricted to base. Returns None for plain glob strings.
