Struct SqlState 

pub struct SqlState(pub [u8; 5]);

5-character SQLSTATE code wrapper. Stored as a fixed [u8; 5] so it’s Copy, fits in a register, and can be compared with a single ==.

Tuple Fields

0: [u8; 5]

Implementations

impl SqlState

pub const fn new(s: &str) -> SqlState

Build from a string literal at compile time. Caller is responsible for ensuring the input is exactly 5 ASCII characters; non-ASCII / wrong length panics in debug, truncates in release.

pub fn class(&self) -> &str

Return the 2-character class prefix as a string slice.

pub fn as_str(&self) -> &str

Render as a stack-allocated string for display.

Trait Implementations

impl Clone for SqlState

fn clone(&self) -> SqlState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SqlState

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

Formats the value using the given formatter.

impl Display for SqlState

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

Formats the value using the given formatter.

impl Hash for SqlState

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SqlState

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