Struct SystemUserId 

pub struct SystemUserId(String);

The name of a user on a Unix system

The username may only contain characters in the set of alphanumeric ASCII characters and the -, or _ character.

Tuple Fields

0: String

Implementations

impl SystemUserId

pub fn new(user: String) -> Result<Self, Error>

Creates a new SystemUserId

Errors

Returns an error if user contains chars other than alphanumeric ones, -, or _.

Examples

use signstar_config::SystemUserId;

SystemUserId::new("user1".to_string())?;
SystemUserId::new("User_1".to_string())?;
assert!(SystemUserId::new("?ser-1".to_string()).is_err());

Trait Implementations

impl AsRef<str> for SystemUserId

fn as_ref(&self) -> &str

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

impl Clone for SystemUserId

fn clone(&self) -> SystemUserId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SystemUserId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SystemUserId

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SystemUserId

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

Formats the value using the given formatter.

impl From<SystemUserId> for String

fn from(value: SystemUserId) -> Self

Converts to this type from the input type.

impl FromStr for SystemUserId

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for SystemUserId

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 PartialEq for SystemUserId

fn eq(&self, other: &SystemUserId) -> 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 Serialize for SystemUserId

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<String> for SystemUserId

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: String) -> Result<Self, Self::Error>

Performs the conversion.

impl Zeroize for SystemUserId

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.

impl Eq for SystemUserId

impl StructuralPartialEq for SystemUserId
