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(t: String) -> 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.

Trait Implementations

impl Eq for Type

impl PartialEq 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 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 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.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

impl PartialOrd 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.

impl Default for Type

fn default() -> Self

Returns the "default value" for a 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.
