Struct AvroParseOptions

pub struct AvroParseOptions<'a> {
    pub schema: Option<&'a Schema>,
    pub relax_numeric: bool,
}

Options for parsing an AvroValue into Datum, with an optional avro schema.

Fields

schema: Option<&'a Schema>

Currently, this schema is only used for decimal.

FIXME: In theory we should use resolved schema. e.g., it’s possible that a field is a reference to a decimal or a record containing a decimal field.

relax_numeric: bool

Strict Mode If strict mode is disabled, an int64 can be parsed from an AvroInt (int32) value.

Implementations

impl<'a> AvroParseOptions<'a>

pub fn create(schema: &'a Schema) -> Self

impl<'a> AvroParseOptions<'a>

fn extract_inner_schema(&self, key: Option<&str>) -> Option<&'a Schema>

pub fn convert_to_datum<'b>( &self, value: &'b Value, type_expected: &DataType, ) -> AccessResult<DatumCow<'b>>

where 'b: 'a,

Parse an avro value into expected type.

3 kinds of type info are used to parsing:

• type_expected. The type that we expect the value is.
• value type. The type info together with the value argument.
• schema. The AvroSchema provided in option.

Cases: (FIXME: Is this precise?)

• If both type_expected and schema are provided, it will check both strictly.
• If only type_expected is provided, it will try to match the value type and the type_expected, converting the value if possible.
• If only value is provided (without schema and type_expected), the DataType will be inferred.

Trait Implementations

impl<'a> Clone for AvroParseOptions<'a>

fn clone(&self) -> AvroParseOptions<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.
