Struct NonBlankString 

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

A source string that holds at least one non-whitespace character.

A selection id, an external document identity and a native name are read back and compared as text. A run of spaces names nothing, so it is refused here rather than by each reader.

Implementations

impl NonBlankString

pub fn new(value: impl Into<String>) -> Option<Self>

Constructs a source string that is not blank.

Absent when the value holds no non-whitespace character, the empty string included.

pub fn prefixed(prefix: NonWhitespaceChar, suffix: impl Display) -> Self

Constructs a non-blank string from a leading character and a suffix.

Total: the prefix is non-whitespace, so the result holds it whatever the suffix renders to.

pub fn with_suffix(&self, suffix: &str) -> Self

Append text while retaining the admitted non-whitespace character.

pub fn as_str(&self) -> &str

Returns the source string.

pub fn into_string(self) -> String

Consumes the value and returns the source string.

Trait Implementations

impl Borrow<str> for NonBlankString

Lookup by the plain string the key spells.

Ord and Hash are derived over the same String, so a map keyed by this type answers get, contains_key and indexing with a &str and orders its keys exactly as a String key would.

fn borrow(&self) -> &str

Immutably borrows from an owned value.

impl Clone for NonBlankString

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NonBlankString

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NonBlankString

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for NonBlankString

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

Formats the value using the given formatter.

impl Eq for NonBlankString

impl Hash for NonBlankString

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 Ord for NonBlankString

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for NonBlankString

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

Equality operator ==.

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

Inequality operator !=.

impl PartialEq<&str> for NonBlankString

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

Equality operator ==.

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

Inequality operator !=.

impl PartialEq<str> for NonBlankString

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for NonBlankString

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for NonBlankString

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
