Trait FieldWrite 

pub trait FieldWrite {
    // Required methods
    fn write_field(
        &self,
        b: BinaryObjectBuilder,
        name: &str,
    ) -> BinaryObjectBuilder;
    fn field_type_code() -> i32;
}

Serialise a single field’s value into a BinaryObjectBuilder.

Required Methods

fn write_field(&self, b: BinaryObjectBuilder, name: &str) -> BinaryObjectBuilder

Write self as field name, returning the builder for chaining.

fn field_type_code() -> i32

The Ignite wire type code for this field’s value.

Dyn Compatibility

This trait is not dyn compatible.

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

impl FieldWrite for Vec<String>

Maps onto Ignite’s STRING_ARRAY, which is nullable-element (Vec<Option<String>> at the IgniteValue level). Writing produces an array with every element present (Some); reading a null element is a TypeMismatch (expected "String", got "Null") since Vec<String> has no representation for an absent element — use Vec<Option<String>> directly (not yet implemented) if nulls must round-trip.

impl<T: FieldWrite> FieldWrite for Option<T>

None writes as IgniteValue::Null (the field is present but null, rather than omitted) so the schema always includes it. On read, both a null value and a missing field map to None.
