Trait Behavior 

pub trait Behavior: Sync {
    // Required methods
    fn columns(&self) -> &'static [Field];
    fn written(&self, write: &Write<'_>, values: &mut [SqlValue]);

    // Provided methods
    fn guards(&self) -> bool { ... }
    fn hides(&self) -> Option<&'static str> { ... }
    fn broadcasts(&self) -> bool { ... }
    fn searched(&self) -> bool { ... }
    fn planned(&self, write: &Write<'_>, plan: &mut Plan<'_>) -> Result<()> { ... }
    fn name(&self) -> &'static str { ... }
}

Never runs I/O.

Required Methods

fn columns(&self) -> &'static [Field]

Stored after the id and before the aggregate’s own fields.

fn written(&self, write: &Write<'_>, values: &mut [SqlValue])

Provided Methods

fn guards(&self) -> bool

fn hides(&self) -> Option<&'static str>

fn broadcasts(&self) -> bool

fn searched(&self) -> bool

fn planned(&self, write: &Write<'_>, plan: &mut Plan<'_>) -> Result<()>

Runs once every behavior has set its columns.

fn name(&self) -> &'static str

Names the behavior in errors, which see it only as dyn Behavior.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
