impl<'de> Deserialize<'de> for Field77T

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Get field format specification

fn parse_with_variant( value: &str, _variant: Option<&str>, _field_tag: Option<&str>, ) -> Result<Self>

where Self: Sized,

Parse field value with variant hint for enum fields Default implementation falls back to regular parse

fn valid_variants() -> Option<Vec<&'static str>>

Get valid variant letters for enum fields Returns None for non-enum fields, Some(vec) for enum fields
