Possible flags for plugin variables

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ReadOnly = 512

Variable is read only

NoServerVariable = 1_024

Variable is not a server variable

NoCliOption = 2_048

No command line option

NoCliArg = 4_096

No argument for the command line

RequiredCliArg = 0

Required CLI argument

OptionalCliArg = 8_192

Optional CLI argument

Deprecated = 16_384

Variable is deprecated

Implementations

impl SysVarOpt

pub const fn as_plugin_var_info(self) -> i32

Trait Implementations

impl Clone for SysVarOpt

fn clone(&self) -> SysVarOpt

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for SysVarOpt

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
