Struct PgSequenceOptions 

pub struct PgSequenceOptions { /* private fields */ }

PostgreSQL sequence options using simple numeric primitives.

Implementations

impl PgSequenceOptions

pub const fn with_increment( self, increment: i64, ) -> Result<Self, PgSequenceError>

Sets the increment.

Errors

Returns PgSequenceError::InvalidIncrement when increment is zero.

pub const fn with_bounds( self, min_value: Option<i64>, max_value: Option<i64>, ) -> Self

Sets min and max labels.

pub const fn with_start(self, start: i64) -> Self

Sets the start value.

pub const fn with_cache(self, cache: u64) -> Result<Self, PgSequenceError>

Sets the cache value.

Errors

Returns PgSequenceError::InvalidCache when cache is zero.

pub const fn with_cycle(self, cycle: bool) -> Self

Sets the cycle flag.

pub const fn increment(self) -> i64

Returns the increment.

pub const fn min_value(self) -> Option<i64>

Returns the min value label.

pub const fn max_value(self) -> Option<i64>

Returns the max value label.

pub const fn start(self) -> i64

Returns the start value.

pub const fn cache(self) -> u64

Returns the cache value.

pub const fn cycle(self) -> bool

Returns the cycle flag.

Trait Implementations

impl Clone for PgSequenceOptions

fn clone(&self) -> PgSequenceOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PgSequenceOptions

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

Formats the value using the given formatter.

impl Default for PgSequenceOptions

fn default() -> Self

Returns the “default value” for a type.

impl Hash for PgSequenceOptions

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

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 Ord for PgSequenceOptions

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

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

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PgSequenceOptions

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

impl PartialOrd for PgSequenceOptions

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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