The custom options a field may carry.

Fields

key: Option<String>

The key as written in the document, when the proto field name cannot spell it.

required: bool

The key must be present.

const_value: Option<String>

The exact string the value must equal.

pattern: Option<String>

The anchored expression the value must match.

min_length: Option<u64>

Least length of a string; 1 means “not blank”.

min_items: Option<u64>

Least number of items of a repeated field.

minimum: Option<i64>

Inclusive lower bound of an integer.

maximum: Option<i64>

Inclusive upper bound of an integer.

heading: Option<String>

For a body section: the heading text.

level: Option<u64>

For a body section: the number of leading hashes.

non_empty: bool

For a body section: it must carry content, not only exist.

Trait Implementations

impl Clone for FieldOptions

fn clone(&self) -> FieldOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FieldOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FieldOptions

fn default() -> FieldOptions

Returns the “default value” for a type.

impl Eq for FieldOptions

impl PartialEq for FieldOptions

fn eq(&self, other: &FieldOptions) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
