Fields

aliases: &'a BTreeMap<String, String>

Alias definitions (original BTreeMap - kept for compatibility).

is_matrix_cell: bool

Whether this is a matrix cell (enables ditto).

is_id_column: bool

Whether this is the ID column.

prev_row: Option<&'a [Value]>

Previous row values (for ditto).

column_index: usize

Column index (for ditto).

current_type: Option<&'a str>

Current type name (for reference resolution context).

version: (u32, u32)

HEDL version (for version-specific validation).

null_char: char

Null literal character (from %NULL directive, defaults to ‘~’).

expected_type: Option<ExpectedType>

Expected type hint from schema or context.

column_types: Option<&'a [ExpectedType]>

Column types for matrix rows.

strict_types: bool

Whether to enforce strict type matching.

error_recovery: bool

Whether to collect all errors or fail fast.

Implementations
