Struct State 

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

A buffer large enough to hold an SOLState for diagnostics

Tuple Fields

0: [u8; 5]

Implementations

impl State

pub const INVALID_STATE_TRANSACTION: State

Can be returned from SQLDisconnect

pub const INVALID_ATTRIBUTE_VALUE: State

Given the specified Attribute value, an invalid value was specified in ValuePtr.

pub const INVALID_SQL_DATA_TYPE: State

An invalid data type has been bound to a statement. Is also returned by SQLFetch if trying to fetch into a 64Bit Integer Buffer.

pub const STRING_DATA_RIGHT_TRUNCATION: State

String or binary data returned for a column resulted in the truncation of nonblank character or non-NULL binary data. If it was a string value, it was right-truncated.

pub const INDICATOR_VARIABLE_REQUIRED_BUT_NOT_SUPPLIED: State

StrLen_or_IndPtr was a null pointer and NULL data was retrieved.

pub const OPTION_VALUE_CHANGED: State

Can be returned by SQLSetStmtAttr function. We expect it in case the array set size is rejected.

pub const INVALID_ATTRIBUTE_OR_OPTION_IDENTIFIER: State

One of two things:

• The value specified for the argument Attribute was not valid for the version of ODBC supported by the driver.
• The value specified for the argument Attribute was a read-only attribute.

Both are emitted by the driver manager, rather than the driver itself.

One example of this error code emitted is when using mdbtools. When the driver builds its dispatch table, it comments out SQLSetStmtAttr triggering unixODBC to use the fallback behavior implemented against SQLSetStmtOption. SQLSetStmtOption does not have any notion of array parameters, so setting the parameter size triggers this error code.

pub fn from_chars_with_nul(code: &[SqlChar; 6]) -> Self

Drops terminating zero and changes char type, if required

pub fn as_str(&self) -> &str

View status code as string slice for displaying. Must always succeed as ODBC status code always consist of ASCII characters.

Trait Implementations

impl Clone for State

fn clone(&self) -> State

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for State

impl Debug for State

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

Formats the value using the given formatter.

impl Default for State

fn default() -> State

Returns the “default value” for a type.

impl Eq for State

impl PartialEq for State

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