Fields

source: Cow<'a, str>

source table or view

projection: Vec<Cow<'a, str>>

fields to include in the result

filter: Option<Cow<'a, str>>

filter condition (the WHERE clause)

order: Option<Cow<'a, str>>

sort order (the ORDER BY clause)

cursor: Option<Cow<'a, str>>

previous page cursor, in base64 (right now this is just the number of items to skip)

page_size: u64

page size

Trait Implementations

impl<'a> Clone for SqlQuery<'a>

fn clone(&self) -> SqlQuery<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for SqlQuery<'a>

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

Formats the value using the given formatter.

impl<'a> Default for SqlQuery<'a>

fn default() -> SqlQuery<'a>

Returns the “default value” for a type.

impl<'de, 'a> Deserialize<'de> for SqlQuery<'a>

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
__D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> PartialEq<SqlQuery<'a>> for SqlQuery<'a>

fn eq(&self, other: &SqlQuery<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> Serialize for SqlQuery<'a>

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

Serialize this value into the given Serde serializer.
