Struct DbName 

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

A validated database name — the only thing a workspace resolves.

Construct it with DbName::parse; there is no other way in, which is what makes “a name is not a path” a property of the type rather than a rule somebody has to remember at every call site.

Implementations

impl DbName

pub fn parse(s: &str) -> Result<Self, WorkspaceError>

Validates s as a database name.

The rule: ASCII, first character [a-z0-9], the rest [a-z0-9_-], length 1..=MAX_DB_NAME.

Errors

WorkspaceError::BadName carrying the specific NameProblem.

pub fn as_str(&self) -> &str

The name as a string slice.

impl PartialEq for DbName

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for DbName

fn partial_cmp(&self, other: &DbName) -> 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
