Trait CsvField 

pub trait CsvField: Sized {
    // Required methods
    fn encode_field(&self) -> String;
    fn decode_field(input: &str) -> Result<Self, CsvDecodeError>;
}

A scalar value that maps to and from a single CSV field.

Encoding never fails — every supported value has a text form. Decoding is strict: the field text must parse exactly into the target type.

Implemented for the integer types, bool ("true"/"false"), String, and Option<T> (an empty field decodes to None).

Required Methods

fn encode_field(&self) -> String

Encodes self into a field value.

fn decode_field(input: &str) -> Result<Self, CsvDecodeError>

Decodes a field value into Self, or returns a CsvDecodeError.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
