Struct FromQueryExpr 

pub struct FromQueryExpr {
    pub variable: String,
    pub source: Box<Expr>,
    pub clauses: Vec<QueryClause>,
    pub select: Box<Expr>,
}

LINQ-style from query expression Syntax: from var in source [clauses…] select expr

Fields

variable: String

Loop variable name (e.g., “t” in “from t in trades”)

source: Box<Expr>

Source expression (e.g., “trades”)

clauses: Vec<QueryClause>

Query clauses (where, order by, group by, join, let)

select: Box<Expr>

Final select expression

Trait Implementations

impl Clone for FromQueryExpr

fn clone(&self) -> FromQueryExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FromQueryExpr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FromQueryExpr

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FromQueryExpr

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
