Struct Field

pub struct Field {
    pub name: String,
    pub type: i32,
    pub table: String,
    pub org_table: String,
    pub database: String,
    pub org_name: String,

    pub column_type: String,
}

Field describes a single column returned by a query

Fields

name: String

name of the field as returned by mysql C API

type: i32

vitess-defined type. Conversion function is in sqltypes package.

table: String

Remaining fields from mysql C API. These fields are only populated when ExecuteOptions.included_fields is set to IncludedFields.ALL.

org_table: String

database: String

org_name: String

column_length: u32

column_length is really a uint32. All 32 bits can be used.

charset: u32

charset is actually a uint16. Only the lower 16 bits are used.

decimals: u32

decimals is actually a uint8. Only the lower 8 bits are used.

flags: u32

flags is actually a uint16. Only the lower 16 bits are used.

column_type: String

column_type is optionally populated from information_schema.columns

Implementations

impl Field

pub fn type(&self) -> Type

Returns the enum value of type, or the default if the field is set to an invalid enum value.

pub fn set_type(&mut self, value: Type)

Sets type to the provided enum value.

Trait Implementations

impl Clone for Field

fn clone(&self) -> Field

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Field

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Field

fn default() -> Self

Returns the “default value” for a type.

impl Message for Field

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Field

fn eq(&self, other: &Field) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
