Struct Maker 

struct Maker<'a> {
    resolver: Resolver<'a>,
    use_utf8view: bool,
    strict_mode: bool,
}

Resolves Avro type names to AvroDataType

See https://avro.apache.org/docs/1.11.1/specification/#names

Fields

resolver: Resolver<'a>

use_utf8view: bool

strict_mode: bool

Implementations

impl<'a> Maker<'a>

fn new(use_utf8view: bool, strict_mode: bool) -> Self

fn make_data_type<'s>( &mut self, writer_schema: &'s Schema<'a>, reader_schema: Option<&'s Schema<'a>>, namespace: Option<&'a str>, ) -> Result<AvroDataType, ArrowError>

fn parse_type<'s>( &mut self, schema: &'s Schema<'a>, namespace: Option<&'a str>, ) -> Result<AvroDataType, ArrowError>

Parses a AvroDataType from the provided Schema and the given name and namespace

name: is the name used to refer to schema in its parent namespace: an optional qualifier used as part of a type hierarchy If the data type is a string, convert to use Utf8View if requested

This function is used during the schema conversion process to determine whether string data should be represented as StringArray (default) or StringViewArray.

use_utf8view: if true, use Utf8View instead of Utf8 for string types
