Struct indradb::Type

pub struct Type(pub String);

An edge or vertex type.

Types must be less than 256 characters long, and can only contain letters, numbers, dashes and underscores.

Methods

impl Type

pub fn new<S: Into<String>>(s: S) -> ValidationResult<Self>

Constructs a new type.

Arguments

• t - The type, which must be less than 256 characters long.

Errors

Returns a ValidationError if the type is longer than 255 characters, or has invalid characters.

pub unsafe fn new_unchecked<S: Into<String>>(s: S) -> Self

Constructs a new type, without any checks that the name is valid.

Arguments

• t - The type, which must be less than 256 characters long.

Safety

This function is marked unsafe because there's no verification that the type name is valid.

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Type

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

Formats the value using the given formatter.

impl Default for Type

fn default() -> Self

Returns the "default value" for a type.

impl Eq for Type

impl FromStr for Type

type Err = ValidationError

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 Type

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, 

Feeds a slice of this type into the given [Hasher].

impl Ord for Type

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

This method returns an [Ordering] between self and other.

#[must_use] fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use] fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use] fn clamp(self, min: Self, max: Self) -> Self

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

Restrict a value to a certain interval.

impl PartialEq<Type> for Type

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

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

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

This method tests for !=.

impl PartialOrd<Type> for Type

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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