Struct google_run1::Expr

pub struct Expr {
    pub description: Option<String>,
    pub expression: Option<String>,
    pub location: Option<String>,
    pub title: Option<String>,
}

Represents a textual expression in the Common Expression Language (CEL) syntax. CEL is a C-like expression language. The syntax and semantics of CEL are documented at https://github.com/google/cel-spec.

Example (Comparison):

title: "Summary size limit"
description: "Determines if a summary is less than 100 chars"
expression: "document.summary.size() < 100"

Example (Equality):

title: "Requestor is owner"
description: "Determines if requestor is the document owner"
expression: "document.owner == request.auth.claims.email"

Example (Logic):

title: "Public documents"
description: "Determine whether the document should be publicly visible"
expression: "document.type != 'private' && document.type != 'internal'"

Example (Data Manipulation):

title: "Notification string"
description: "Create a notification string with a timestamp."
expression: "'New message received at ' + string(document.create_time)"

The exact variables and functions that may be referenced within an expression are determined by the service that evaluates it. See the service documentation for additional information.

This type is not used in any activity, and only used as part of another schema.

Fields

description: Option<String>

Optional. Description of the expression. This is a longer text which describes the expression, e.g. when hovered over it in a UI.

expression: Option<String>

Textual representation of an expression in Common Expression Language syntax.

location: Option<String>

Optional. String indicating the location of the expression for error reporting, e.g. a file name and a position in the file.

title: Option<String>

Optional. Title for the expression, i.e. a short string describing its purpose. This can be used e.g. in UIs which allow to enter the expression.
