Enum Preset 

pub enum Preset {
    DenyEverything,
    ReadOnly,
    ReadWrite,
    FullDdl,
    AllowEverything,
}

Predefined permission presets for common access control configurations.

Each variant maps to an AuthorizationResolver constructor that sets sensible defaults for a particular use case. Variants are ordered from most restrictive to least restrictive. The preset is selected via the --preset CLI flag and determines the baseline permissions before any --allow / --deny overrides are applied.

Variants

DenyEverything

Denies all operations. Useful as a starting point when every permitted action must be explicitly allowed via --allow flags.

ReadOnly

Allows reads, selects, transactions, SQL functions, recursive CTEs, and pragmas. Denies all data modification and DDL.

ReadWrite

Extends read-only with insert, update, delete, savepoints, analyze, reindex, and temporary object operations. Permanent DDL, attach, and detach remain denied.

FullDdl

Extends read-write with permanent DDL (create/drop tables, indexes, triggers, views, and alter table). Attach, detach, and virtual table operations remain denied.

AllowEverything

Allows all operations with no restrictions. Intended for development and testing only.

Trait Implementations

impl Clone for Preset

fn clone(&self) -> Preset

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Preset

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

Formats the value using the given formatter.

impl Default for Preset

fn default() -> Preset

Returns the “default value” for a type.

impl Display for Preset

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

Formats the value using the given formatter.

impl From<Preset> for AuthorizationResolver

Converts a Preset into the corresponding AuthorizationResolver by calling the matching constructor.

fn from(preset: Preset) -> Self

Converts to this type from the input type.

impl FromStr for Preset

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Preset, <Self as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for Preset

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 Preset

fn cmp(&self, other: &Preset) -> 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 Preset

fn eq(&self, other: &Preset) -> 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 Preset

fn partial_cmp(&self, other: &Preset) -> 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<&str> for Preset

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Preset, <Self as TryFrom<&str>>::Error>

Performs the conversion.

impl ValueEnum for Preset

fn value_variants<'a>() -> &'a [Self]

All possible argument values, in display order.

fn to_possible_value<'a>(&self) -> Option<PossibleValue>

The canonical argument value.

fn from_str(input: &str, ignore_case: bool) -> Result<Self, String>

Parse an argument into Self.

impl Copy for Preset
