Method try_array_shape_completion

src/completion/handler.rs:870–883

Try to offer known array shape keys when the cursor is inside `$var['` or `$var["`. Returns `None` when the cursor is not in an array-key context or when no shape keys could be resolved.

        content: &str,
        position: Position,
        ctx: &FileContext,

    /// when no shape keys could be resolved.
