Struct NonEmptyText

pub struct NonEmptyText(/* private fields */);

A string type that guarantees non-empty content.

This type wraps a String and ensures it contains at least one non-whitespace character. The input is automatically trimmed of leading and trailing whitespace during construction.

Implementations

impl NonEmptyText

pub fn new(input: impl AsRef<str>) -> Result<NonEmptyText, TextError>

Creates a new NonEmptyText from the given input.

The input is trimmed of leading and trailing whitespace. If the trimmed result is empty, an error is returned.

Arguments

• input - Any type that can be converted to a string reference

Returns

Returns Ok(NonEmptyText) if the trimmed input is non-empty, or Err(TextError::Empty) if it’s empty or contains only whitespace.

pub fn as_str(&self) -> &str

Returns the inner string as a string slice.

pub fn starts_with(&self, pattern: &str) -> bool

Checks if the text starts with the given pattern.

pub fn contains(&self, pattern: &str) -> bool

Checks if the text contains the given pattern.

Trait Implementations

impl AsRef<str> for NonEmptyText

fn as_ref(&self) -> &str

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

impl Clone for NonEmptyText

fn clone(&self) -> NonEmptyText

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NonEmptyText

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NonEmptyText

fn deserialize<D>( deserializer: D, ) -> Result<NonEmptyText, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for NonEmptyText

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

Formats the value using the given formatter.

impl Hash for NonEmptyText

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 NonEmptyText

fn eq(&self, other: &NonEmptyText) -> 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 NonEmptyText

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
