Implementations

impl Field

pub fn new(level: u8, name: String) -> Self

Create a new field with level and name

pub fn with_kind(level: u8, name: String, kind: FieldKind) -> Self

Create a new field with all parameters

pub fn is_group(&self) -> bool

Check if this is a group field

pub fn is_scalar(&self) -> bool

Check if this is a scalar (leaf) field

pub fn effective_length(&self) -> u32

Get the effective length including any arrays

pub fn sign_separate(&self) -> Option<&SignSeparateInfo>

Returns SIGN SEPARATE info if this is a zoned decimal field with that clause.

pub fn is_packed(&self) -> bool

Returns true if this is a packed decimal (COMP-3) field.

pub fn is_binary(&self) -> bool

Returns true if this is a binary integer (COMP/BINARY) field.

pub fn is_filler(&self) -> bool
