Struct odbc_api::Bit

pub struct Bit(pub u8);

New type wrapping u8 and binding as SQL_BIT.

If rust would guarantee the representation of bool to be an u8, bool would be the obvious choice instead. Alas it is not and someday on some platform bool might be something else than a u8 so let’s use this new type instead.

Implementations

impl Bit

pub fn as_bool(self) -> bool

Maps 1 to true, 0 to false. Panics if Bit should be invalid (not 0 or 1).

Trait Implementations

impl CData for Bit

fn cdata_type(&self) -> CDataType

The identifier of the C data type of the value buffer. When it is retrieving data from the data source with fetch, the driver converts the data to this type. When it sends data to the source, the driver converts the data from this type.

fn indicator_ptr(&self) -> *const isize

Indicates the length of variable sized types. May be zero for fixed sized types.

fn value_ptr(&self) -> *const c_void

Pointer to a value corresponding to the one described by cdata_type.

fn buffer_length(&self) -> isize

Maximum length of the type in bytes (not characters). It is required to index values in bound buffers, if more than one parameter is bound. Can be set to zero for types not bound as parameter arrays, i.e. CStr.

impl Clone for Bit

fn clone(&self) -> Bit

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Bit

impl Debug for Bit

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

Formats the value using the given formatter.

impl Default for Bit

fn default() -> Bit

Returns the “default value” for a type.

impl Eq for Bit

impl HasDataType for Bit

fn data_type(&self) -> DataType

The SQL data as which the parameter is bound to ODBC.

impl InputParameter for Bit

impl Ord for Bit

fn cmp(&self, other: &Bit) -> Ordering

This method returns an Ordering between self and other.

#[must_use]

pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]

pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]

pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<Bit> for Bit

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<Bit> for Bit

fn partial_cmp(&self, other: &Bit) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]

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

This method tests less than (for self and other) and is used by the < operator.

#[must_use]

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]

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

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
