Struct CreateView 

pub struct CreateView {
    pub view_name: ValueOrGlob<String>,
}

Selector for CREATE VIEW statements.

String syntax examples

• CreateView – any view.
• CreateView(active_users) – only active_users.

Fields

view_name: ValueOrGlob<String>

The name of the view being created, or * for any.

Implementations

impl CreateView

pub fn new(view_name: impl Into<ValueOrGlob<String>>) -> Self

Creates a new CreateView with the provided field values.

Each argument accepts any type that implements Into<ValueOrGlob<T>>, so callers can pass a raw value, a ValueOrGlob, or an Option<T>.

pub fn empty() -> Self

Creates a CreateView where every field is a Glob, matching all possible values.

pub fn with_view_name(self, value: impl Into<ValueOrGlob<String>>) -> Self

Sets CreateView::view_name and returns self for method chaining.

The name of the view being created, or * for any.

pub const fn is_all_glob(&self) -> bool

Returns true if every field on this CreateView is a Glob.

pub const fn is_all_value(&self) -> bool

Returns true if every field on this CreateView is a Value.

pub const fn is_any_glob(&self) -> bool

Returns true if at least one field on this CreateView is a Glob.

pub const fn is_any_value(&self) -> bool

Returns true if at least one field on this CreateView is a Value.

pub const fn specificity(&self) -> usize

Returns the number of Value fields on this CreateView, used to rank competing policy rules during resolution. A higher specificity means the rule targets a narrower set of operations.

pub fn matches(&self, view_name: &(impl PartialEq<String> + ?Sized)) -> bool

Returns true if this selector covers the given field values. A Glob field matches any value; a Value field matches only when equal.

Trait Implementations

impl Clone for CreateView

fn clone(&self) -> CreateView

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CreateView

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

Formats the value using the given formatter.

impl Default for CreateView

Defaults to CreateView::empty, producing a selector where every field is a glob.

fn default() -> Self

Returns the “default value” for a type.

impl Display for CreateView

Formats this CreateView using the CLI selector syntax. When all fields are globs, renders the bare identifier CreateView; otherwise renders the identifier with parenthesized dot-separated fields.

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

Formats the value using the given formatter.

impl From<CreateView> for AccessControlSelector

Converts a CreateView into its corresponding AccessControlSelector variant.

fn from(value: CreateView) -> Self

Converts to this type from the input type.

impl From<CreateView> for String

Converts a CreateView into its string representation via Display.

fn from(value: CreateView) -> Self

Converts to this type from the input type.

impl FromStr for CreateView

Parses a selector string into a CreateView. Accepts the syntax CreateView or CreateView(field1.field2).

type Err = AccessControlSelectorParseError

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 CreateView

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 CreateView

fn cmp(&self, other: &CreateView) -> 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.

impl PartialEq for CreateView

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for CreateView

fn partial_cmp(&self, other: &CreateView) -> 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 TryFrom<String> for CreateView

Parses an owned String into a CreateView by delegating to FromStr.

type Error = AccessControlSelectorParseError

The type returned in the event of a conversion error.

fn try_from(v: String) -> Result<Self, Self::Error>

Performs the conversion.
