Enum ParameterStyle 

#[repr(i32)]
pub enum ParameterStyle {
    Unspecified = 0,
    S = 1,
}

The parameter-passing style.

Variants

Unspecified = 0

S = 1

The parameters are passed positionally (S = SQL).

Implementations

impl ParameterStyle

pub const fn is_valid(value: i32) -> bool

Returns true if value is a variant of ParameterStyle.

pub fn from_i32(value: i32) -> Option<ParameterStyle>

👎Deprecated:

Use the TryFrom<i32> implementation instead

Converts an i32 to a ParameterStyle, or None if value is not a valid variant.

impl ParameterStyle

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

pub fn from_str_name(value: &str) -> Option<Self>

Creates an enum from field names used in the ProtoBuf definition.

Trait Implementations

impl Clone for ParameterStyle

fn clone(&self) -> ParameterStyle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ParameterStyle

impl Debug for ParameterStyle

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

Formats the value using the given formatter.

impl Default for ParameterStyle

fn default() -> ParameterStyle

impl StructuralPartialEq for ParameterStyle

impl TryFrom<i32> for ParameterStyle

type Error = UnknownEnumValue
