}

A built-in generator, chosen by type/name inference or set with SeedConfig::kind.

New kinds may be added in any release, so a match on it needs a _ arm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

IntPrimaryKey

Sequential integers starting at 1 (row index + 1).

Int

Random integer from 0 to 10 000.

Float

Random number from 0 up to 10 000, rounded to 2 decimals.

Bool

Random boolean.

Text

5 to 50 random lowercase letters.

FirstName

First name from a built-in list.

LastName

Last name from a built-in list.

FullName

First and last name.

Email

first.last{row}@example.com (or another domain reserved for testing); the row index keeps emails unique.

Phone

US-style phone number, (555) 555-5555.

City

City name from a built-in list.

Country

Country name from a built-in list.

Address

Street address, 123 Name Street.

JobTitle

Job title from a built-in list.

Title

A short sentence-case phrase, such as a post title: Dolor sit amet.

Url

https:// URL on a reserved example domain; the row index keeps URLs unique.

Username

Lowercase first_last{row}; the row index keeps usernames unique.

Slug

URL slug, dolor-sit-amet-{row}; the row index keeps slugs unique.

Company

Company name: a last name and a suffix, such as Smith Inc.

LoremIpsum

Ten words of lorem ipsum.

Uuid

Random UUID v4 as text (8-4-4-4-12 hex).

Json

Small JSON object as text.

Date

Date between 2000 and 2030 as YYYY-MM-DD; for an integer column type, its Unix milliseconds (UTC midnight) instead.

Timestamp

Timestamp between 2000 and 2030 as YYYY-MM-DD HH:MM:SS; for an integer column type, its Unix milliseconds (UTC) instead.

Time

Time of day, HH:MM:SS.

TimeTz

Time of day with a UTC offset, HH:MM:SS+HH.

Interval

PostgreSQL interval of 1 to 72 hours, such as "12 hours".

Blob

32 random bytes.

PgInet

PostgreSQL INET

PgCidr

PostgreSQL CIDR

PgMacAddr

PostgreSQL MACADDR

PgMacAddr8

PostgreSQL MACADDR8

PgPoint

PostgreSQL POINT

PgLine

PostgreSQL LINE

PgLseg

PostgreSQL LSEG

PgBox

PostgreSQL BOX

PgPath

PostgreSQL PATH

PgPolygon

PostgreSQL POLYGON

PgCircle

PostgreSQL CIRCLE

PgBit

PostgreSQL BIT: 8 random bits.

PgVarBit

PostgreSQL VARBIT: 1 to 32 random bits.

PgArray

PostgreSQL array: always the empty array literal {}.

Implementations

impl GeneratorKind

pub fn into_generator(self) -> Box<dyn Generator>

Returns the generator for this kind.

Trait Implementations

impl Clone for GeneratorKind

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for GeneratorKind

impl Debug for GeneratorKind

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

Formats the value using the given formatter.

impl Eq for GeneratorKind

impl Generator for GeneratorKind

A built-in kind is itself a generator, so it can be passed wherever a Generator is expected.

fn generate( &self, rng: &mut dyn RngCore, index: usize, sql_type: &str, ) -> SeedValue

Returns the value for row index (0-based). sql_type is the column’s SQL type as declared, e.g. "INTEGER" or "TEXT".

fn name(&self) -> &'static str

Returns a short name for debugging. Defaults to the type name.

impl PartialEq for GeneratorKind

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

Equality operator ==.

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

Inequality operator !=.
