Struct Placement 

pub struct Placement {
    pub constraints: Option<BTreeSet<String>>,
    pub preferences: Option<BTreeSet<Preferences>>,
}

Specifies constraints and preferences for the platform to select a physical node to run service containers. See more: https://docs.docker.com/reference/compose-file/deploy/#placement

Fields

constraints: Option<BTreeSet<String>>

Defines a required property the platform’s node must fulfill to run the service container.

preferences: Option<BTreeSet<Preferences>>

Defines a strategy (currently spread is the only supported strategy) to spread tasks evenly over the values of the datacenter node label.

Trait Implementations

impl Clone for Placement

fn clone(&self) -> Placement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Placement

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

Formats the value using the given formatter.

impl Default for Placement

fn default() -> Placement

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Placement

where Placement: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Placement

fn eq(&self, other: &Placement) -> 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 Serialize for Placement

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Placement

impl StructuralPartialEq for Placement
