Struct Operations 

#[non_exhaustive]
pub struct Operations {
    pub dependency_targets: Vec<Target>,
    pub disabled: bool,
    pub tags: Vec<String>,
    pub relation_descriptor: Option<RelationDescriptor>,
    pub queries: Vec<String>,
    pub has_output: bool,
    /* private fields */
}

Represents a list of arbitrary database operations.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

dependency_targets: Vec<Target>

A list of actions that this action depends on.

disabled: bool

Whether this action is disabled (i.e. should not be run).

tags: Vec<String>

Arbitrary, user-defined tags on this action.

relation_descriptor: Option<RelationDescriptor>

Descriptor for any output relation and its columns. Only set if has_output is true.

queries: Vec<String>

A list of arbitrary SQL statements that will be executed without alteration.

has_output: bool

Whether these operations produce an output relation.

Implementations

impl Operations

pub fn new() -> Self

pub fn set_dependency_targets<T, V>(self, v: T) -> Self

where T: IntoIterator<Item = V>, V: Into<Target>,

Sets the value of dependency_targets.

pub fn set_disabled<T: Into<bool>>(self, v: T) -> Self

Sets the value of disabled.

pub fn set_tags<T, V>(self, v: T) -> Self

where T: IntoIterator<Item = V>, V: Into<String>,

Sets the value of tags.

pub fn set_relation_descriptor<T>(self, v: T) -> Self

where T: Into<RelationDescriptor>,

Sets the value of relation_descriptor.

pub fn set_or_clear_relation_descriptor<T>(self, v: Option<T>) -> Self

where T: Into<RelationDescriptor>,

Sets or clears the value of relation_descriptor.

pub fn set_queries<T, V>(self, v: T) -> Self

where T: IntoIterator<Item = V>, V: Into<String>,

Sets the value of queries.

pub fn set_has_output<T: Into<bool>>(self, v: T) -> Self

Sets the value of has_output.

Trait Implementations

impl Clone for Operations

fn clone(&self) -> Operations

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Operations

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

Formats the value using the given formatter.

impl Default for Operations

fn default() -> Operations

Returns the “default value” for a type.

impl Message for Operations

fn typename() -> &'static str

The typename of this message.

impl PartialEq for Operations

fn eq(&self, other: &Operations) -> 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.
