Struct PrimaryKey 

#[non_exhaustive]
pub struct PrimaryKey {
    pub name: Option<String>,
    pub offset: i32,
    pub length: i32,
}

The primary key for a KSDS data set.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: Option<String>

A name for the Primary Key.

offset: i32

A positive integer value representing the offset to mark the start of the primary key in the record byte array.

length: i32

A strictly positive integer value representing the length of the primary key.

Implementations

impl PrimaryKey

pub fn name(&self) -> Option<&str>

A name for the Primary Key.

pub fn offset(&self) -> i32

A positive integer value representing the offset to mark the start of the primary key in the record byte array.

pub fn length(&self) -> i32

A strictly positive integer value representing the length of the primary key.

impl PrimaryKey

pub fn builder() -> PrimaryKeyBuilder

Creates a new builder-style object to manufacture PrimaryKey.

Trait Implementations

impl Clone for PrimaryKey

fn clone(&self) -> PrimaryKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrimaryKey

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

Formats the value using the given formatter.

impl PartialEq for PrimaryKey

fn eq(&self, other: &PrimaryKey) -> 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.
