Struct EnvVarName 

pub struct EnvVarName { /* private fields */ }

An owned, validated environment variable name.

Implementations

impl EnvVarName

pub fn new(name: impl Into<String>) -> Result<EnvVarName, EnvVarNameError>

Creates a validated environment variable name.

Errors

Returns EnvVarNameError when name is empty or contains unsupported characters.

pub fn as_str(&self) -> &str

Returns the environment variable name.

Trait Implementations

impl AsRef<str> for EnvVarName

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for EnvVarName

fn clone(&self) -> EnvVarName

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EnvVarName

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

Formats the value using the given formatter.

impl Display for EnvVarName

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

Formats the value using the given formatter.

impl Hash for EnvVarName

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

where __H: Hasher,

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 PartialEq for EnvVarName

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